disturbing film scene involving boy puncturing hands

[blink_babe13]

this is really vague but i hope it rings a bell with someone! i distinctly remember this scene from a film. it features a young boy (maybe around 8/9) in a classroom, he calls to someone (his teacher i think) and then proceeds to bring his hands down on those spikes used in restaurants to hold the bills on, puncturing his hands. any ideas???

i believe it is the butterfly effect.
