The family that slides together, stays together — at least, that’s what Scott Disick is hoping for after a rough patch with Kourtney … because yesterday, the guy put in some serious bonging time at a street fair. The Lord, Kourt and son Mason appeared to be one big, happy family as they hit ride after ride at a carnival in the Hamptons … including one of those huge slides and a teacup-thingy. It’s a big deal for Scott — who got left in the cold last by Kourtney last month when he was kicked out of their Hamptons home for partying too much.
