WHO ARE YOU????!!! (a Mik From Mik and Mak Joke)

Mik walked home from work and saw 4 people dressed in grim reaper suits. He ran home. The next time,the next time and 6 more walks for home, he decided to confront them. He yelled "who ARE you"????!!! They chased him into a wall. "s-s- Show yourself" he squeaked. They took their masks off and yelled "Hi, we're the wiggles!"
