I believe that's called the Tickle-Me-Elmo: Extreme version. [shudder]
"Again! Again!" I've heard that before...
I remember when the original TME was finally in stock at (store's name omitted.) As annoying as those things were it was still fun to walk down the plush toys aisle & poke every one of them things in the belly.
shimatta1 is already working on the Cthulhu version for me.
I dunno, I'm really amused by how the responses get progressively more ridiculous as you tickle him more. I'm not sure how I'd make that work for Cthulhu. Perhaps if you tickle him too often, you get eaten.
In the three original Warcraft games, clicking on a character to select it would always elicit a response. The first one was always "Yes?" or "Sire?" or (in the case of the orcs) "What?" If you clicked more than once, the responses would get more and more annoyed.
In Warcraft II (and III, I assume) you could record your own customized dialogue, which is a funnier idea in theory than it is in practice.
