J falls to the floor

We were eating dinner last night and everything was quiet and going smoothly when all of a sudden J falls out of his chair to the floor.Everyone just looked at each other and we hear from under the table this little voice say, "It's okay, I can eat down here." At this we start laughing. If anyone hasn't figured it out yet J is the comedian in the house. Do you think he might get his joking nature from my grandmother (Mamaw) or maybe Pops?
