Alex's new silly phrase

Last week Alex started answering every request with "Yes, Sir!" and that includes saying it to me. I try to correct him to say 'yes mommy' or 'yes, ma'am', but it doesn't really work.

Jason and I were trying to figure out where in the world he learned such polite manners...and then it clicked one night when we were reading one of his favorite books:

"Please, sir. I don't like this trick, sir.
My tongue isn't quick or slick, sir.
I get all those ticks and clocks, sir,
mixed up with the chicks and tocks, sir.
I can't do it, Mr. Fox, sir. I'm so sorry, Mr. Knox, sir."

It doesn't say 'yes, sir' anywhere in Fox in Socks...but this has to be where he learned it. So, thank you, Dr. Seuss, for helping teach my boy manners ;)
