The Royal Institution, a British organization dedicated to science education and research, made a video about how to stop being ticklish, and it looks like it works. I don't know if it actually works, since it would be weird to ask someone in the office to tickle me right now, but I'm just going to trust them. All you have to do is put your hands over the hands of the person tickling you.
