The Wall (1979)

“Pink.”
“What?”
“Where's the door hole?”
“It goes right there. See? I drew it with the magic marker.”
“You were supposed to cut it out with the power saw.”
“Dude, I'm gonna.”
“Oh, really?”
“Yes!”
“So, go get the power saw.”
“Okay, I will.”
[Pink runs into the wall, realizing he can't get out]
“I see the problem.”
“OH, DO YA?”
