The "dumbening"

[.:4:.]

This one only works once and only if you have good repore with the bar staff at your local. Not generational at all. Buy drinks, pay with a 20, get your change then say 'i paid with a $30 note'. They will go straight back to the till then 5 seconds later laugh and reply with something along the lines of '**** you're an idiot'. Yeah they are right but i find it funny at the time.
