Best run I ever put together was when I ran three 8 ball racks flat on a 9' table, I thought I was hot shit... Then I had a guy run 7 racks flat on me to make 20 bucks, that was when I realized I was in the wrong business
Here is a fun hustle though, for anyone who is interested in messing with their friends a bit. This is designed to work on a full size table, so it may backfire if you are playing on a beat up bar table with shitty cushions. If the bar table is in good shape it should still work even though it is a shorter table with wider pockets.
Take the cue ball and two other balls, and get rid of the rest of the balls. On the side rail of the table(as opposed to the shorter end rail) place the two balls on the rail touching each other about a foot from the corner pocket. Now take the cue ball and set it somewhere on the felt within a foot or two of the balls and closer to the end rail, basically at an angle as opposed to being on the rail as well. The whole idea is that you are going to shoot the cue ball into the first ball and combo the second ball across the middle pocket all the way down the table into the opposite end corner pocket.
So here is where it gets fun... You set them up and give it a smack, shooting the ball into the corner (because you're awesome right!?), then set 'em up for them and let them give it a shot, which they won't make. Let them try a few times, then take over and with ease knock it in again yourself. Repeat as necessary, They will be amazed and confused at first, but quickly get upset while they try to figure out how the hell you can do it every time, but they can't even make it once.
The rub: the physics involved make this shot literally impossible to make if you don't know the secret. They will be trying to figure out what english is necessary to make it, but it doesn't matter, they can try all day and they won't make it. That's what makes it so funny! The secret is that while they are shooting the shot, you are standing behind them where they cannot see that you are getting spit on your finger before every time it's your turn. When it is your turn you simply grab the two balls and stealthily put a little spit on one of them and then make that the spot where the two balls touch. The reduced friction created by the spit will then make the ball go straight in to the pocket.
Pretty simple, hopefully my long winded explanation makes sense? This is a really fun hustle if you set up the scenario right, and you will have someone, preferably a really good shooter with a soon to be bruised ego, really upset.
