Captain Underpants

The fearless sergeant at the Battle of Gettysburg, who single-handedly vanquished the entire Confederate army in one swift fart. Unfortunately, he was killed in battle, and is still remembered to this day as the nudest hero of the Civil War. He was buried in his own soil in Piqua, Ohio.

David: I just read about the one and only Captain Underpants.
Jake: He was such a great man.
Both: Amen

underpants gnomes

Small characters made up on the show South Park. The underpants gnomes are small gnomes that sneak into your house at night to steal your underpants and somehow make a profit out of it.

Gaaaaah! The underpants gnomes are stealing my last pair of tighty whities.
