Betelgeuse answering Barbara and Adam's question about his qualifications...
Betelgeuse: (calm, plain voice) Ah. Well, I attended Juilliard. I'm a graduate of the Harvard Business School. I travel quite extensively. (returns to character's normal voice) I lived through the Black Plague and had a pretty good time during that! (chewing scenery) I've seen The Exorcist ABOUT A HUNDRED AND SIXTY-SEVEN TIMES, AND IT KEEPS GETTING FUNNIEREVERY SINGLE TIME I SEE IT! NOT TO MENTION THE FACT THAT YOU'RE TALKING TO A DEAD GUY!!! NOW WHAT DO YOU THINK?!? ...you think I'm qualified?
The following scene where Betelgeuse gets asked "Are you scary?"
Betelgeuse: What do you think of this? (camera shifts behind him as something happens to his face as it explodes) (Barbara and Adam both freak out) Betelgeuse (back to normal): You like it?
Also a "blink-and-you'll-miss-it" moment where after Adam asks if Betelgeuse can be scary, he turns around and subtly insults Adam by calling him a "jerkoff" by making a jerking motion with his hand.
The scene in which Betelgeuse kicks a tree in the model and knocks it over before yelling "Nice fucking model!" and grabbing himself in a rather obscene way. I was laughing so hard from the "Honk Honk" sound effects.
Especially the straight face he makes while he goes "Honk Honk".
Betelgeuse trying to sneak a peak under Barbara's dress by lifting it with a tree branch.
Delia: Open this door, you dead people, or we'll bust it down and we'll drag you out by the ropes you hang yourselves with! Lydia: Shh! They didn't commit suicide. Delia: It doesn't matter. [Lydia rolls her eyes] Lydia, I have a chance to teach you something here: you have got to take the upper hand in all situations or people, whether they're dead or alive, will walk all over you.
After spending a good portion of the episode getting them recaptured (after dehydrating them since they grow in water), Lydia wonders what BJ did with the "Party People In-A-Can".
