IQ or no IQ

In a bar a guy says I have an IQ or 181
Another one answers I have an IQ of 182
They get together and start a conversation about nuclear physics
Further along the bar someone says I have an IQ of 121
Someone else says I have an IQ of 122
They get together and begin a conversation about music
After a few seconds of silence one hears I have an IQ of 2
and then an answer I have an IQ of 3
They get together and talk about One Nation!
