I thought it was sad that we had no pun lessons at school. This is much more fun than writing essays on the Apartheid.
No kidding! Apparently there is a universal here when it comes to school. We never had such fun either, even when learning Spanish, which I barely can speak now.
I was lucky to have a couple of punny parents and am pretty bad with them myself. Witness my radio airname — Rosa Corn with the show's title being In Your Ear. I think that's pretty self explanitory as a pun to an ESL fellow such as yourself. (But it will never be as nutty as the surely/shirley, that one's a classic.)
P.S. Thanks for the Zoo tip, I'll give it a search.
It is my opinion and I am unanimous in this, because it is my opinion, which is, in fact, mine.
