that is nothing!
back in 7th grade, i was handing out flyers during my presentation to the class. On the flyer there was a woman who was bending over with a lens to look at some drawing on the floor...
After my presentation, i got bored, so i drew a guy behind her, and a guy in front of her, vividly expressing what a "Double team" is.
After the class was over, my teacher found that drawing on the floor. Next class she had a very serious face and demanded us to tell who "drew the nasty image" (this is 7th grade).
Nobody moved... she yelled the same thing this time..
I get up and say, "All i know is i brought these flyers here.. why the hell would anyone do something like this is beyond me".. and sat back down.
She tortured us for another 5 minutes then dropped the subject.
