No Good Deed Goes Unpunished
Anything that can go wrong, will go wrong.
The other line always moves faster.
Everyone has a scheme for getting rich that will not work.

If you're feeling good, don't worry, you'll get over it.
Hilarious, and so true! Don't miss your chance at this one - limited quantity remains in stock.
