I don't know if this is the worst greeting card I've ever seen -- Hallmark or otherwise -- but it's pretty close. There is no way to your affection to a girl experiencing an unplanned pregnancy than to send her a card like this.
La bruja de Monterrey = the witch from Monterrey, MX.
I'm pretty sure that it's a plastic bag or something like that. The video is in Spanish, but most of the dialogue is clear enough to understand without subtitles (if you speak some Spanish).
Still, it's entertaining! I still can't believe how many people believe in martians, the occult, witches, warlocks, UFO's, etc around the world. It's a throwback to an earlier age, I guess.
