The next time you see a POTUS autocade rolling by, & you don't know what to do, here are some hand signs you can employ:
Hand Jive or Mudra, when you see that fleet go by, raise a hand or two, & give the guy some sign.
Dance your ass off & be joyous!
Peace, Love, Rock! & Hang loose, bruddah & sistrah!
We Luv Ya, Mon!
Somewhere over the rainbow We'll win by and by.
