Corrected entry: When Miss Desiree is dancing at the party, Rudy takes a deep drink from a bottle of liquor. Most of us would appreciate this performance with a liquor. We even see bubbles come up, but as he takes the bottle away from his mouth, he is still holding it upside down. Doing this normally, the content would be spilled on his face, so he probably didn't drink at all.
Corrected entry: When Debbie's father is at the party and tells Rick that Debbie will break it off when she finds out about the party, O'Neil tells him that there's a phone in the back bedroom. Debbie's father then leaves, presumably to use the phone. O'Neil then asks all the hookers to follow him and they go after Debbie's father. Then Debbie arrives at the party dressed as a hooker. Rick's friends recognize her and tell Rick who says "Go up to her like you don't know who she is and send her into the back bedroom". They do so but when Debbie gets to the back bedroom its empty. Shouldn't her father, O'Neil and the hookers be in there?
