Something that has worked for me in the past is to take out a gobble shaker and pump it a few times. It's not going to work every time, but I've called a few stubborn gobblers in with it, along with a few yelps. I also like to scratch the leaves. Seems like scratching leaves always gets their attention. Of course, there is always that gobbler who won't commit regardless of what you do, but it's sure fun trying to get him committed.
