There's a Harley-Davidson bumper sticker that I think sums up being SLY, it reads:
"If I have to explain, you wouldn't understand"

You've spared us a mouthful of words. I rubbed my bald dome in your honor. Professor Melon

With everyone who takes notice, for better(head rubs) or worse(explaining the look), isn't that just one more person we've introduced to the world of the SLY?
That sir, (yeah I know you work for a living) is some very wise thinking.
I had this jolly old client in here one day who kept calling me Onionhead (from some old movie) and rubbing my head to tease me. I knew it was in good fun, but my scalp is for young female hands only!
I would consider it a compliment if it was me. Here is a description of the movie Onionhead.
Griffith is cast as Al Woods, a college student majoring in girls and parties. When his grades drop and his relationship with girlfiend Jo Hill (Erin O'Brien) sours, Al joins the Coast Guard as assistant cook on the SS Periwinkle, fully expecting to sit out WW2 in peace and quiet. Instead, he runs afoul of navy protocol in general and mess officer Red Wildoe (Walter Matthau) in particular. In or out of trouble, Al remains a stubborn individualist, and it is this quality that attracts him to Wildoe's erstwhile fiancee Stella.
Still could keep the hands off the noggin though!!
The RobMeister is "middle aged"? You said it, not me!!
No, I didn't. 
The worst people in the world for making these kinds of wisecracks are middle-aged men (50s and 60s) -- either because they are delighted to see someone else lose their hair, or -- if they still have most of their hair themselves.
Come up with smartass comebacks in advance.
Remark: "Dude yer bald"
Explanation: "Yeah, and yer stupid....but I can grow my hair back"
Um, I was referring to the people who make the offending remarks in the first place, not the people making the smartass comebacks, like Robmeister.
