Masonic Stockings?

Bro John and Bro Mike are getting dressed and ready for a lodge meeting.

When John takes his apron out of the case, Mike notices a pair of silk stockings unrolling and hanging out of the case.

Mike asks: "I say, John, what's this with the ladies stuff ?"

John gives a quick look and whispers: "You remember the installation meeting last year ?"

Mike acknowledges and John goes on:

"Keep it a secret, but on the way home I stopped at the pub on where I met this lovely female. Apparently she lost her stockings in my car, and my wife found them. I told her I was passed to a higher degree, and ever since she takes 'm out of the case washes them and puts them back in with my gloves!"
