The Incredible Hulk
Thaddeus Ross is drinking his sorrows away in a bar when Tony Stark comes for a visit. He asks to talk to Thunderbolt about a new team he's putting together. This is, of course, referencing the Avengers movie which was already in production. This was entirely improvised, and they both only got two rules for the filming of it (one of them was probably to mention the Avengers!)
