While driving around Al's Toy Barn, the gang drives down the Buzz Lightyear aisle. Tour Guide Barbie tells them "Back in 1995 short-sighted retailers did not order enough dolls to meet demand". This is an in-joke and a fact: When the original Toy Story (1995) was released, toy sellers did not think the movie would be a hit and they indeed did not order enough dolls to keep up with demand. The joke is also a self-deprecating dig at Mattel Toys, which denied use of the Barbie character in the first film, thinking it would be a flop.
