He just shakes it off.
He doesn't need to tell him to shake the martini.
Shake It Off
To see if there was any more money in the kitty !
He likes his drinks shaken, not stirred.
I mean, seriously, are they seeing anyone?
What I mean: "I'm off to smoke a bowl in my car so I can deal with all of you."
One with Parkinson's disease!
They shake hands.
