Mojo sitting with (on) a visitor

I had a visitor over at the house, yesterday. He said he loved dogs,
so, he was cool with Mojo's way of showing affection. When we all
decided to sit down and talk, Mojo laid down on the couch, too -
except my guest was already on the couch, so, Mojo did what he does
best...he jumped up on the couch and laid across him. Good thing he
liked dogs. Mojo will really test your limits of how close he can
get. He'd be happy if he could climb up into your shirt and go to
sleep. He really thrives on human companionship - typical pit bull
behavior from what I know.
