Monkey Patcher

I like everything with monkeys so when I ran across that I thought it would neatly fit in here:

"Monkey Patching is the ability to hack out a solution over someone else nice code. Interpreted languages like ruby or php always get this, since you get the source, not a binary. Now there are lots of bad things about Monkey Patching, but it's really useful when you need it. Now I understand that if you don't have source, Monkey Patching is not so practical."
