Actually, they're not funny at all with the possible exceptions of Ricky Gervais and one-fourth of the Kids in the Hall. But sometimes, as you will see in the following video, they are accidentally funny. When a couple of unfunny foreigners try to pull an unfunny prank on a naked sleeping foriegn pal, the result is an unintentional delight of funniness. Mmmm... even though the floppy naughty bits are edited out, I'm gonna call this NSFW-ish.
