A woman is held by the legs by a Graboid tentacle while a man holds her by the arms, trying to pull her free. During the struggle, she refuses to remove her pants to escape and reveals the fact that she is not wearing underwear. Afterwards she further explains she does not regularly wear underwear because she finds it restrictive, even while she works and lives near the Arctic. The man listening to her reveals he's attracted to her more because of this fact.
A man is asked to urinate from a tower onto the ground below as a noise distraction to the Graboids. His genitals are not shown. Only a large urine stream is shown at varying distances. Another man cracks a joke about building an arc from the "arcing" urine stream.
