Several years ago, and by several I mean over 25, I was on the phone with my mother. I’m at work and we’re have ourselves a chat. She mentions something to me that is of obvious knowledge to which I respond, “No duh!”
Mom, never having heard that term before, is curious. “I’ve heard of ‘Duh'”, she said, “but I’ve never heard “No duh'”. I’m astonished. I thought everyone had heard of that. I went on to explain that they mean the same thing. No duh means duh. Duh?
To prove my point, I tell my mom that I’m going to get my brother on the phone to show her that he knows what it means. I get my brother on a 3-way conversation. Mom knows this; my brother does not.
“Hey, man, what’s going on?” I ask. Nothing, whatever. We talk a couple of minutes and then I get him to tell me something that is common knowledge. I say, “No duh!”. “FUCK YOU!”, comes from the other end of the line. After a short silence I tell my brother that mom is also on the phone. Mom mournfully tell us both, “I think I’m going to hang up now”. We didn’t know whether to laugh or cry.
Now I still think this is a funny (and true) story. I’ve told it many times, much to my brother’s chagrin. In the order of funniness this story ranks, I say it goes: me, my brother, my mother.
