I have long touted Albino Blacksheep as a great source for Flash animations, but while they're current, their archives are too extensive to search, especially several months out. So I was elated to find the "Fun 4 Friends" archive at Sundog Productions. They have some of my old favorites (including the piano stripper that I can't link to here), as well as some new fun, like "Elmo meets Tigger" and "Squigo" and a supposedly real Dutch commercial that's over 8 MB but worth the fun.
