A classic. I gave it a 10. "Mercenary Man" could not have been played (or made fun of) enough for me. Borgnine with an awful accent as a brilliant scientist = too good to be true. The weird comic relief soldiers.
An embarrassment of riches. Riffing was hilarious.
I think my favorite (non-Mercenary Man related) riff might be when the love interest makes some lame wisecrack after killing some bad guys and Mike says, "yeah, those men had families."
