T-Shirt face, I need answers

There's this baby picture of me I've seen a thousand times. But I was just examining it closely and have some questions for my dad. You see, it appears to be a studio portrait. The background and lighting make me thing this. But then I started to wonder what I'm sitting on, and I realize it's legs. Somebody in jeans is laying on the floor and I'm sitting on them. I can see the top of the pants way over to the right and a touch of belly and yellow shirt. WHO IS THIS!?!? Why am I sitting on them? Why are they lying in my professional portrait? Does anyone else think this is odd?
