Some thoughts to pun-der:
1. A dentist and a manicurist got married. They fought tooth and nail.
2. Show me a piano falling down a mineshaft and I’ll show you A-flat miner.
3. When you’ve seen one shopping center, you’ve seen a mall.
4. A bicycle can’t stand alone. It is two-tired.
5. The guy who fell onto an upholstery machine was fully recovered.
