“Where do you find stewed tomatoes?”/“Try the salad bar.”

People get “stewed” (drunk) at a bar. There’s a pun:
 
Shopper: I’m looking for stewed tomatoes.
Clerk: Try the salad bar.

 
The joke has been cited in print since at least 2008.

“Just how hard is it to find jokes specifically about tomatoes? Well, we didn’t have to look much further than the University of California-Davis’ Web site. Take a look at these and let us know if they make you laugh — or cry. Why did the Tomato go out with a prune? Because he couldn’t find a date! How do you fix a broken tomato? Tomato paste! Why was the tomato blushing? Because it saw the salad dressing. Shopper: I’m looking for STEWED tomatoes. Clerk: Try the salad BAR.
