'Betty White's Off Their Rockers': Nuns flash their boobs for breast awareness

Those salacious seniors are up to their old people tricks again Wednesday (May 2) on NBC's "Betty White's Off Their Rockers," and this time the clothes are coming off -- and revealing old lady undergarments.

In the sneak-peek clip above, two nuns try an innovative approach to raising money for breast awareness. And for only $1, donors become very aware of breasts indeed.  

Also on deck this week: A man decides to make his own alterations on a shirt he likes in a store, and an old man escapes blame for insulting a security guard. Also, one prankster enlists a friendly stranger to help secure his car -- with tape, and another helps himself to someone else's meal at a restaurant.

"Betty White's Off Their Rockers" airs Wednesday at 8 p.m. on NBC.
