Something else I learned, one of the riffs is a deleted line from the script.
The riff: During the scene where Thor beats up the SHIELD guys at the hammer site the computer guy's talking about the storm and Kevin's line is, "Oh, and I think we're sterile now."
The script: At the diner when the locals are talking about the hammer one of them mentions how it could be radioactive. The next line (in the movie he gets interrupted by Thor) is, "I'm probably sterile now."
There's actually a lot of tacky jokes they left out. We should be thankful.
