“This is why you don’t steal watermelons!”

robotlabs over on Reddit has spotted a great sign:

“Rat urine injected in watermelon for a biology project? Um, okay”, writes EDdmike.

“This is the best revenge for something like this even if it wasn’t poisoned. A watermelon is not worth the effort to hunt down the perpetrator but something like this will have him/her panicking for weeks and regretting their life choices”, notes fantomknight1.

“But it looked so good .. I don’t feel so good now”, says torontogirl98.
