Worst thing you could do. Uses up all the air.

[Patti has left Ingrid trapped in a closet with only a transmitter to contact Kelso with] Ingrid Randall:
Mr. Kelso, if you don't mind, Let's get going. [Kelso is in the other room with D.C] Zeke Kelso:
It's not 8:00 yet. [realizes that it's only him and D.C. in the room] Zeke Kelso:
Say that again. Ingrid Randall:
Let's get going. [D.C. sneezes at the same time] Zeke Kelso:
[worried]
Now, wait a minute. Let's just... try and pull ourselves together here a minute. Ingrid Randall:
PATTI, YOU LITTLE WRETCH! Let me out of here! Zeke Kelso:
Oh! [Using his tracker, Kelso finds the room where Ingrid is] Ingrid Randall:
[pounding on the door]
Patti! Let me out of here! Zeke Kelso:
I'll get you out. Patti's gone to the movies. Ingrid Randall:
Gone to the movies? Zeke Kelso:
[trying the door]
Something seems to be stuck here. Ingrid Randall:
Well, open it! There's no air! I'm suffocating! Zeke Kelso:
I'll go get a screwdriver. [as he's going downstairs, he sees D.C. exit the house] Ingrid Randall:
I'm suffocating! Let me out of here! Zeke Kelso:
[whispering]
I'm sorry, but the cat's going out, I've got to follow it. Ingrid Randall:
Don't you dare follow that cat! Get me out of here. [pounding] Ingrid Randall:
There's no air! Zeke Kelso:
I'll be back just as soon as I can. Probably just an hour or two. Lie down on the floor. There's usually more air there. Ingrid Randall:
I'm gonna scream! Zeke Kelso:
[going downstairs]
Worst thing you could do. Uses up all the air. [Ingrid screams. Startled, Kelso runs back upstairs to get her out]
