My husband used to fall asleep in class all the time. One teacher ushered the class out into the hall, set all the clocks to 5pm, and then they watched.
There was MUCH taunting and laughter when he finally woke up, drool all over his cheek, looking like an ass.
Maybe he should have sued for the Teacher hurting his self esteeeeeeem.... get a Whambulance!!!!!
