binning
Placing the smallest bloke in the class in a bin arse-first, so far that it comes up to his knees and armpits, and his hands flap uselessly outside. Then lift the bin, place it on the teacher's desk, and await his arrival. Often, the child would panic, and fall off the desk, leaving him semi-conscious in a pile of rubbish on the floor as the teacher entered the room. This is more incriminating, as it simply looks like the kid went mental in the bin, and lost consciousness through rubbish-related hyperventilation.

When we hit upper sixth and were thus old enough to know better, it was decided that due to my being short, I should become The Bin Woman.
This surprisingly voluntary title involved removing the bin from its wooden home (like a McDonald's bin), and I would sit in there, throwing rubbish back through the flap.
It wasn't that funny, the dinner lady got pissed off, and I got beans in my hair.

A horizontal variation on binning involved trapping Ben Egan in a small cupboard with glass sliding doors. After we got bored of looking at him, we turned the cupboard to face the wall.

Once you have someone in a bin, they're fairly helpless, so you can stage scenes around them.

JACQUELINE'S TRYST
1. INT. DAY. CLASSROOM.

Thomas : Good afternoon, Jacqueline. I trust no-one knows you came.
Jacqueline : Of course not. I value my position within the household, such as it is.
Thomas : You should know better than to... oh, is that the new flavour Monster Munch?
Jacqueline : You noticed. To be honest I am a little let down; I fear the flavour has gathered at the bottom of the bag, leaving the crisps themselves flavourless and cloying.
Thomas : Then there is only one thing for it!
Jacqueline : Whatever do you mean?
Thomas : You must spit a mouthful of the offending crisps into this bin!
Jacqueline : But Thomas!
Thomas : But nothing! Spit the crisps into the bin!
Jacqueline : But there is a boy in the bin, Thomas.
Thomas : Yes, that's Steve. We binned him.
[Jacqueline gobs her crisps onto Steve. Thomas takes a handful and does the same]
Both : A hahahahah!
