If you want to screw with someone's head...

Buy them a cake where the icing is blue, very very blue.

Kroger had some adorable little cakes that looked like Cookie Monster's head. They even had a mini cookie sticking out of his mouth. I was charmed. Until the next morning that is.

Seems that a certain blue food coloring can cause your poo to turn green. VERY green. Not brown green, but totally crayon green.

I was honestly freaked out until I googled it, not thinking about the cake at all. Then I had a great laugh. And ate another piece.

This rates up there with eating asparagus, making your pee smell like it.

I used to get similar results from drinking grape soda. I stopped drinking grape soda

I've always had the same results with the (blue) coconut snow cones.

You'd probably get the same results and feel a lot better the next morning if you just went straight to a gay bar and yelled out "Virgin lfg!"
