Hulk was just sitting down, watching TV, and Hulk tuned into this show he likes, called "MAD". It on Cartoon Network and successor to the cancelled Madtv. Hulk saw skit about Hulk and other Avengers. Just watch it and see. It had Hulk laughing hysterically.
That actually WAS Hulk's only gripe with The Avengers. Hulk not get as much screentime as everyone else. So, Hulk can relate to this.
Hulk love this show.
