Playing with ultra-tight players

Playing in a few home games I have run into some ultra-tight, Rock of Gibraltar type players that call with only high pairs or will only see rivers with the nuts. I have found that out of aggravation or just the sadistic desire to see these players lose, I have tried to outdraw these players even to the river.

I know that's what they're hoping for, but man even playing $1-$2 ... loosen up a bit and gamble!
