I was reading natalie, sans h., and came across some really funny French TV ads and clips that she had posted.
The first is for high speed internet, and doesn't really require any translation, other than that. The first one is probably the funnies, but the third one is good too.
The second set of clips are pretty funny too, but require some knowledge of French, or else the jokes won't be funny. If you don't know any French, or it's a bit rusty, check out the site, and click on the "antivol" clip. It's probably one of the funnies clips, and doesn't require any French to get what's going on.
It's best if you check out the clips with high speed internet, because they may take a while to download.
