What jokes can people with strong dialects make when they speak Mandarin?

I went to a restaurant with my leader that day. The boss was addicted to mustard, so he quickly finished a small dish in front of him and waved to the waiter.

The waiter came to him politely, bent down and waited for instructions, knowing that my leader had a strong accent.

Leader: Miss, would you like some? Program? (voice: mustard).

The waiter was shocked: program? What program?

Leader: That's the yellow one ~

The waiter was dumbfounded and embarrassed to say that we don't have yellow programs here.

The leader was in a hurry and gestured with both hands and feet: why not! It's just the exciting kind.
