I think the only rule for puns is that they have to be punny. If you can't think of any puns to punch in, you could always copy one from google, but that wouldn't be right. (kidding, if you can't think of any go right ahead).
The following pun I will be copying right from google: Why did Adele cross the road? To say hello from the other side.
It's a good thing Hitler didn't win World War 2. He wasn't able to take his goals any fuhrer, that wouldn't be reich.
What can ZeoStar do when he turns 21? Go to the ZeoBar. (uh i'm clearly running out of ideas).
