I think it would be JDS for me. Imagine knocking over Junior's beer in a bar and him doing his meet me in the middle gesture... I would fill my pants worse than big Timmy!
There's also the thought at the back of my mind that Cain got put to sleep by JDS. In the same situation with Cain perhaps you could sucker punch him with a bar stool and be lucky enough to put him out rather than him turning your face into mince meat.
After seeing the kind of beating JDS can take I imagine the stool breaking and him just looking angrier. Like in the A-team whenever someone tried to get the jump on BA and smashed something over his head only to further anger him.
