I'm so tickled! Well, the trout is.
Trout tickling has been practiced for many centuries. (Nope, I'm not kidding.) Shakespeare mentioned this curiously named practice in Twelfth Night, saying:
"Close, in the name of jesting! Lie thou there, for here comes the trout that must be caught with tickling."
And in the interest of clarification, trout tickling is defined as "the mystical art of rubbing a trout's underbelly until it goes into a lax, trance-like state." It's apparently similar to catfish noodling, but let's not even go there.
