A organisation of scientists are conducting a survey on what jobs people do in relation to what their IQ is.

After a few years with the survey in progress, they are getting a pretty good idea of what kind of jobs people with certain levels of IQ have.

One day a man comes up and says "My IQ is 150"

"And what is your job?" The scientists ask.

"I'm a computer programmer" comes the reply, and they go off and have a conversation about computer programming.

Then another man comes up and says "My IQs 110"

"And what is your job?" the scientists ask.

"I'm a garbageman." He replies, and they go off and have a conversation about garbage disposal.

Then another man comes up and says "My IQs 60"

"So what sticks do you use?" ask the scientists.
