Fat gal hitchhiker death is one of my all-time favorites in this film. She's just in this one for a few minutes so she can get bumped off and add to the body count.
You've seen Guy Standeven in something because the man was in everything.

I loved her sign, too. I may do one like that for the office Halloween party (I'm leaving soon, so why not?). I took that as they wanted to emphasize the clench effect after being killed.
