What SNL sketch is this? And where can I find it?

It was just on the last episode, and there were three couples in a living room and the one couple's children walk in and they're complete nerds...Kristen Wiig with braces and the Seth Rogen's stomach hanging out of his shirt and pants. Kristen Wiig's character repeatedly says "We....blah blah blah" and then Seth Rogen's character replies, "Me too/either." And Kristen's character replies in a loud tone of voice "I said we!!!!!!" Does anyone know what this is called or if I can find it online to watch anywhere?
