Since today is my birthday (Yay! Still alive!), I thought this week's contest should be party-themed: birthday parties, holidays, general merriment and whooping it up. So, any scene from any TV show, movie or comic showing those types of events, like Worf's birthday party, Walter putting a birthday hat on the cow in Fringe, the Ewok party, the Matrix rave, etc.
Standard bbs av rules apply, and let's keep it work-safe. I'll put the poll up on Tuesday.
Here's mine: Alice and the Unbirthday Cake
