Problem: "Good Vibrations" is a song composed by Brian Wilson with words by Mike Love for the American rock band the Beach Boys, of which both were members. Released on October 10, 1966, the single was an immediate critical and commercial hit, topping record charts in several countries including the US and UK. Characterized by its complex soundscapes, episodic structure, and subversions of pop music formula, it was the costliest single ever recorded at the time of its release. "Good Vibrations" later became widely acclaimed as one of the greatest masterpieces of rock music.

Although the song does not technically contain a theremin, "Good Vibrations" is the most frequently cited example of the instrument's use in pop music. Upon release, the single prompted an unexpected revival in theremins and increased the awareness of analog synthesizers. The notion that "Good Vibrations" features a theremin has been erroneously repeated in books, CD liner notes, and quotes from the recording's participants. While having a similar sound, a theremin is an aerial-controlled instrument, unlike the Electro-Theremin.  When the Beach Boys needed to reproduce its sound onstage, Wilson first requested that Tanner play the Electro-Theremin live with the group, but he declined due to commitments. Tanner recalls saying to Wilson, "I've got the wrong sort of hair to be on stage with you fellas", to which Wilson replied: "We'll give you a Prince Valiant wig." The Beach Boys then requested the services of Walter Sear, who asked Bob Moog to design a ribbon controller, since the group was used to playing the fretboards of a guitar. Sears remembers marking fretboard-like lines on the ribbon "so they could play the damn thing." Moog began manufacturing his own models of theremins. He later noted: "The pop record scene cleaned us out of our stock which we expected to last through Christmas."  In Steven M. Martin's 1993 documentary Theremin: An Electronic Odyssey, in which Wilson makes an appearance, it was revealed that the attention being paid to the theremin due to "Good Vibrations" caused Russian authorities to exile its inventor, Leon Theremin.

Problem: George Armstrong Custer (December 5, 1839 - June 25, 1876) was a United States Army officer and cavalry commander in the American Civil War and the American Indian Wars. Raised in Michigan and Ohio, Custer was admitted to West Point in 1857, where he graduated last in his class in 1861. With the outbreak of the Civil War, Custer was called to serve with the Union Army. Custer developed a strong reputation during the Civil War.

In 1864, with the Cavalry Corps of the Army of the Potomac reorganized under the command of Major General Philip Sheridan, Custer (now commanding the 3rd Division) led his "Wolverines" to the Shenandoah Valley where by the year's end they defeated the army of Confederate Lieutenant General Jubal Early in the Valley Campaigns of 1864. During May and June, Sheridan and Custer (Captain, 5th Cavalry, May 8 and Brevet Lieutenant Colonel, May 11) took part in cavalry actions supporting the Overland Campaign, including the Battle of the Wilderness (after which Custer ascended to division command), and the Battle of Yellow Tavern (where J.E.B. Stuart was mortally wounded). In the largest all-cavalry engagement of the war, the Battle of Trevilian Station, in which Sheridan sought to destroy the Virginia Central Railroad and the Confederates' western resupply route, Custer captured Hampton's divisional train, but was then cut off and suffered heavy losses (including having his division's trains overrun and his personal baggage captured by the enemy) before being relieved. When Lieutenant General Early was then ordered to move down the Shenandoah Valley and threaten Washington, D.C., Custer's division was again dispatched under Sheridan. In the Valley Campaigns of 1864, they pursued the Confederates at the Third Battle of Winchester and effectively destroyed Early's army during Sheridan's counterattack at Cedar Creek.  Sheridan and Custer, having defeated Early, returned to the main Union Army lines at the Siege of Petersburg, where they spent the winter. In April 1865 the Confederate lines finally broke, and Robert E. Lee began his retreat to Appomattox Court House, pursued by the Union cavalry. Custer distinguished himself by his actions at Waynesboro, Dinwiddie Court House, and Five Forks. His division blocked Lee's retreat on its final day and received the first flag of truce from the Confederate force. Custer was present at the surrender at Appomattox Court House and the table upon which the surrender was signed was presented to him as a gift for his wife by General Philip Sheridan, who included a note to her praising Custer's gallantry. She treasured the gift of the historical table, which is now in the Smithsonian Institution.  On April 25, after the war officially ended, Custer had his men search for, then illegally seize a large, prize racehorse "Don Juan" near Clarksville, Virginia, worth then an estimated $10,000 (several hundred thousand today), along with his written pedigree. Custer rode Don Juan in the grand review victory parade in Washington, D.C. on May 23, creating a sensation when the scared thoroughbred bolted. The owner, Richard Gaines, wrote to General Grant, who then ordered Custer to return the horse to Gaines, but he did not, instead hiding the horse and winning a race with it the next year, before the horse died suddenly.
