I think I might be a little in love with notattending.com. It's a site set up by two writers, Haje and Kate, who scripted a fake wedding invitation and asks others – including you, if you like – to RSVP as honestly as you want. My current favorite is from Michael Dietz, who says, "you two picked the exact weekend that my cat is getting married!" and later clarifies, "his mom is coming in from California." And really, how could Kate and Haje expect their friend to dissapoint their...cat's...mother.

I am also fond of this contribution from user germanfreek: "I would love to be there, especially to see how much weight Kate has gained, and how much hair Haje has lost since our last encounter. Remember when you hit my car and didn't leave a note..."
