I've used the same pre-shot routine for years - never varies a bit , but I PROMISE I don't look like a robot .
1) take a hearty swallow of Early Times .
2) stagger up to the table
3) gesture wildly in the air with my cue in the general direction of the intended pocket
4) knock the chalk off the table in an attempt to pick it up .
5)leave the chalk on the floor , stick my cue in it and grind away
6)tilt my head sideways and sqint at the object ball with one eye
7)stroke effortlessly
8)watch the ball roll gracefully into the pocket . . . .
WAIT !! That's the wrong pocket !
and that's not even the object ball -- that's the cue ball !!
9) wait my turn.
10) repeat 1-8 , above
