Wait a second?!?! You mean the deaf woman ACTUALLY "DID" sign "sweep" correctly? This is unusual, because it kind of changes the entire concept of the show. It was Krammer's crap signing skills that caused the confusion, and not the poor lip reading skills of the deaf woman.
This kills the humour of the previous SIX and SEX mixup, and ruins the humour in George's paranoia.
I am shocked!
