It was really funny earlier, it was Dicks birthday, and he wanted a surprise party. This alien hunter woman turned up, gagged him and knocked everyone else unconscious.
So when she was seeing to the people in the basement Dick went to the phone gagged and phoned Marys office, and the sarcastic woman answered. He's just like guh guh guh (that general sound lol) and the woman goes
"oh yeah" "guh guh" "I'm hot" "guh guh guh" "do me" "guh guh!" "do me all night" and hung up. She's saying those lines with a really straight face, and it's so funny to watch.
