My husband is at it again!!!!?

I know I ask a lot of questions concerning my husband and son, but I swear he really is a great dad, just really stupid sometimes! But that's why he has me, to keep him in line! Anyways, last night, I was in our bedroom folding clothes, and my husband and son were in the living room. Our whole house has hardwood floors, the kind where if your in your socks, and get a good running start, you can slide 10 feet! Well, I hear my husband say "One, two, threeeeeeee!!!!" and then my son starts laughing like a maniac! Then he does it again, and they are both laughing their heads off now! So, I walk around the corner to see whats going on, and peek so they can't see me. My son was in long sleeve and long legged PJ's, and my husband is on his knees, and my son is laying on the floor in front of him. He then proceeds to do his 1,2,3 count, and pushes my son with both hands and he slides across the floor, and then crashes into a big pile of pillows!! Well, I had to be the party-pooper, and stop the game, because I was afraid someone was going to get hurt, and it was also time for bed. I also have to change my sons PJ's because of the dust and dirt from the floor (time to sweep and mop the floors again!!) Have you ever walked in on someone doing something funny with your baby? Whether it was something sweet, or something like my husband was doing!
