I have heard of the tickle method but I just used the reach into the water, got my hand underneath the trout and quickly yanked my hand up and flipped the trout out on the grass.

AND at the risk of angering alot of the female readers (NO I am not a male chauvinist), I have to say that even my wife, who had never fished in her life, was able to get several fish out of the creek too. I am sure this is the preferred method used by the bears at Whitney Portal and was definitely the method by the Grizzlies at our Zoo in town.
