Input: Text: this course of events took place when i was in middle school, but i think it's worthy of this subbreddit.
 
it was the week before christmas, and every year my mother would send me with a gift for my home room teacher. this year, my mother was putting together a secret santa with her co-workers. they had the option of either sending a "normal" gift or a "naughty" gift.  as i rushed out the door to catch the bus, i grabbed the gift bag i believed contained an assortment of meats and cheeses.  thinking nothing of it, i sat the gift on my (very attractive female) teacher's desk. she began opening my gift in front of the entire class. what she pulls out is no arrangement of meats and cheeses, but a pair of pink furry handcuffs.  she immediately bursts out laughing and runs out of the classroom to show her co-workers. i wasn't sure to feel humiliation or like a straight up bawler; needless to say my mother was quite devastated.  this story traveled far, and ended up winning me "the most embarrassing moment" award upon graduation. good grief.

TIFU by giving my teacher the wrong gift.
