If you’ve never heard of Teeth, this comic will probably be funnier if you check out the movie’s website. You still might not find the comic funny, but I can’t find any links that would take you someplace you could buy a sense of humour, so you’re pretty much out of luck (Zing!).
Thankfully, I’m not a dad yet, but if I were to be one, and if I had a daughter, once she got to dating age this move would only be second to cleaning-my-shotgun-in-the-living-room in my campaign to keep any penisai out of her. And maybe something to do with fire ants for the third. I dunno, I don’t want to think about it…
