Okay, new game. Just post the beginning of a proverb and give it a new ending.
For example:
Original:
If at first you don't succeed, ... try and try again
Modified:
If at first you don't succeed, ... kill Jared Leto.
Except make it funny, instead of stupid. You can use the same proverb someone else has used, and you can post as many versions of any proverb as you like. Go.
