Laugh til your ribs hurt!

It's not often something makes me laugh until my ribs hurt. Laughing so much, you cannot get air, and it becomes painful. The clearest time I remember, was watching Mytery Science Theater do "The Attack of the the Eye People" (two the's). It was just after Joel said, "It's not really much of an attack. More like, the minor vandalism of the eye people."

More recently, it was the Daily WTF: http://thedailywtf.com/Articles/Unsolved_Murder.aspx

Not sure why exactly. Maybe something I remember from college, "It is an honor to die for my employer!"
