Things which tickled my funny bone during this past year (just a quick list, by no means comprehensive):
Bumper sticker: "It takes a village to raise a child -- it takes a viking to raze a village."
Movies:
Wedding Crashers and
The 40 Year-Old Virgin. Both were raunchy, largely "turn on the cameras and improv" comedy, with great supporting players and some scenes or lines that basically test bladder strength.
The one PSP commercial that makes me laugh
every. single. time: "Hey! Come out and play!" "I can't! I'm playing Nut!" "But there's Portable Nut!" "Whaaaaaaat?" (I don't know why, but that one just takes the cake for me...)
EDIT: Forgot the best one of all. Just the fact that
this movie is even being made. And
this webcomic about the movie. And
this fake trailer transcript. And
this LJ coverage. I mean, really, it's a cult film already and it's not even out yet. How can you go wrong with a title like that?
