My favorite celebrity encounter occured about 12-15 years ago.  My buddy and I walked into a 24-hour diner in NYC after a long evening out.  As we walked in, we say Willem Dafoe sitting by himself in a booth.  My friend (who was a little buzzed) walked straight up to him and started babbling, "Willem Dafoe!  Holy cow!  It's William Dafoe!  No way, man!"

Just when it looked like Willem Dafoe was going to kill both of us, my friend deadpans, "Dude.  I have ALL your albums!"

Willem Dafoe started cracking up hysterically and ended up paying for our burgers.
