Besides, my dad taught me all the words to "The Bastard King of England" and "The Ball of Kirriemuir". You really think he would balk at a Virgin Sturgeon? (He taught me THAT song too.)
He also taught me to shoot, woodwork, and change a tire. That's what happens when you only have daughters, I guess.
