I have a friend upon which I need to seek revenge! She's always pulling some random prank, so I'm going to saran-wrap her car. And probably her best friend's car too, since she was involved. But I don't think saran-wrap is enough, so perhaps something semi-disgusting. I'm trying not to get something that will cause paint damage, like shaving cream, whip cream, etc. Most of it will probably go on the saran wrap, but I'm thinking of putting some under the door handle that she won't see until after she grabs it. If it causes damage, I can always use some non-damaging suggestions. :-)
