Shaggy Dog, The Easter Egg - Toy Story Reference

I don't know if this is truly an egg or not!

Towards the end of the movie when they are on the way to the courthouse, The Shaggy Dog (played by Tim Allen) is wearing a cape running on a road. As The Shaggy Dog jumps from the bridge onto a moving truck he shouts "To Infinity-And Beyond". A true reference to his Buzz Lightyear character in Toy Story!
