It was a Tyrannosaurus Rex on the mound throwing out the first pitch at the Padres game the other day.  It's not often you see something like this, the dinosaur had a pretty good throw too.  The dinosaur was at the field promoting the stage show Walking With Dinosaurs.  I agree with the commentator that said 'he would like that costume to take home', it would be a blast to wear around the neighborhood and see what reactions you get.
