This is something I thought of ever since July.
Mr. Tickle meets Mr. Rush and calls him "Mr. Zippy" because of what Mr. Grumpy told him and wants to give him a welcome tickle. However, Mr. Rush isn't very happy when he called him "Zippy" and goes on being a motormouth to Mr. Tickle.
This is based on this scene from a show called "Transformers Animated" where Bumblebee meets Blurr for the first time. [link]
I don't know if anyone might like this since no one cares about the Mr. Men fandom anymore.
