Goldberg was the neighborhood smart aleck. When he saw the sign in the deli that said We Serve Every Type of Sandwich, he called the waiter over.
"Is that sign true?" Goldberg asked.
"Absolutely, positively! We serve every type of sandwich," the waiter replied proudly.
'Then bring me an elephant sandwich on toast," Goldberg said.
A slight pause and the waiter replied, "I'm sorry, Mr. Goldberg, but for just one sandwich, we can't start another elephant."
