ROFL!
I got called out on my wm9 sub too. It was by my TA who wore a gen Tag Heuer GMT Carrera.
He looked at my wrist and said, "what watch is that?"
I said, "a Rolex, but it's fake" =D
So I let him take a look at it and he responded, "doesn't it supposed to have a display case back?"
And I said, "no no no, it's supposed to have a sticker on the back"/
He was like @_@ " a sticker?" lol
