CHENG CHIN AND HIS WONDERFUL UNDERWEAR

Cheng Chin is lecturing on the board. Cheng Chin's panty lines are clearly revealed through his pants. Student 1, sitting behind Student 2 and next to Student 3, looks at Cheng Chin skeptically. Everyone else in the class is taking notes, noticing nothing strange.

Student 1: (quietly) hey...

Student 2 ignores Student 1.

Student 1: (excessively loud) HEY!
Student 2: (turns around) What?
Student 1: I can't pay attention right now.

Student 2 turns back around and continues to take notes.

Student 1: Hey dude I can't pay attention. All I can see is Cheng Chin's underwear!

Cheng Chin, facing the board and lecturing, reaches to adjust his underwear. Student 1 shakes Student 2 to get his attention.

Student 1: His underwear, man!
Student 2: What the fuck are you talking about?
Student 1: His underwear! Can't you see it?
Student 2: So are you... undressing him with your imagination? I don't get it.
Student 1: No! His underwear! I can see his panties!

Student 2 ignores Student 1, and goes back to taking notes. Fade out. Fade in on the next Cheng Chin lecture. Now Cheng Chin is wearing underwear over his pants. Class is taking notes, again noticing nothing strange.

Student 1: (quietly) hey...
Student 2: (loudly) WHAT!?

Cheng Chin turns around for a second, then goes back to lecturing.

Student 1: Dude I can't pay attention! Can't you see it!?
Student 2: See what? His underwear? No. Shut up.

Student 2 goes back to taking notes. Student 1 turns to Student 3.

Student 1: What about that underwear. Cheng Chin, Calvin Klein model. Amirite?
Student 3: What the fuck are you talking about? 
Student 1: His underwear.
Student 3: What?
Student 1: Can't you see his underwear!? CAN'T ANYONE SEE HIS UNDERWEAR?!

Cheng Chin turns around and stops lecturing. He is very happy.

Cheng Chin: Oh my underwear? You like my underwear? Thank you! 

Cheng Chin, overwhelmed with confidence, turns around, adjusts his underwear, and continues lecturing.
