Hand signal for listers?

[Wolff <wolff_b@ix.netcom.com>]

Hello all,
This week on Monday I saw a red S4 driving in Aptos. Yesterday I saw a
silver A4q drive past me and then about 30 seconds later I saw another
silver A4q go by. We need some kind of hand signal like the "hey bra"
Hawaiian thing with thumb and pinkey finger extended. This way when we
see a q being driven we can find out if the driver is a lister or not.
Best sign I can think of is 4 fingers up for "quattro", but that's not
very elegant.(?)  Any ideas anyone?
