back in 1998 when i was in high school i had a biology teacher who was a raging bull dyke, and it was right around the time that some guy got famous for stopping a dyke from bursting by sticking his finger in a leak that had sprung. we were discussing dams and their effects on ecosystems, so this fat friend of mine, who looked like a 350 pound Harry Potter, raises his hand and says "didn't some guy get famous for sticking his finger in a dyke?". hahahaha she thought it was funny.
