I think they can be really dumb....I was at my grandmas 50th annerversary and it took place in the 2nd story of the bar. Well me, my cuz Tasha and my friend Jen where standing on the belcony out side and somebody walks out and say-
Girl 1- "Lets get on the bus."
guy- "duh....."
Girl 2- "What about the car?"
guy- "duh....."
Girl 1- "We have a car??"
guy- "duh....."
Girl 2- "I thoght so..."
guy- "duh....."

It like you are so dumb I just wanted to spit on them...but my mom said not to provoke them we must have sat there all night listening to the drunks come out of the bar acting stupid.
