If a woman did this prank on my man, I would slap her clear into tomorrow. The prank Kathy Griffen pulled was meant to humiliate Anderson Cooper.
If Cooper has a serious boyfriend or a Significant Other who loves him, that person should take Griffin aside and tell her that if she pulls that again, there will be hell to pay.
That was not funny. That was mean. Cruel, even. She did it because she could get away with it. What a heartless bully she is.
