Hi everybody
I hope someone from The LearnEnglish Team replies to my comment
So, I've already read Jack's explanation but I still don't understand what is the real meaning of "avoidance" in this joke, i.e. what should be the right answer to the question "What's an avoidance?". I think it's something related to law but I'm not sure. Thanks in advance for any help, especially for a clear explanation :D

P.S. I have few jokes (five to be exact - which I took from a school textbook) like the ones you use here - with puns - I would like to share with users of LearnEnglish. What is the best way to do that?

hi!   avoid = to keep away from; keep clear of; shun: to avoid a person; to avoid taxes; to avoid danger, and i suppose you know what means "dance" try to link these works
