It's one of those "intelligence test" jokes, like this one I remember from elementary school:
Two birds were in a bird bath. One bird said "Please pass the soap". The other bird said "What do you think this is, a typewriter?".
(I think Gary Chow was responsible for that gem)
Or this one:
There was a big polar bear floating on a small iceberg. He came across a small polar bear floating on a big iceberg. He yelled to the small polar bear: "When our icebergs are close enough, let's switch" to which the smaller polar bear agreed. When the iceberg's drifted close enough, they both jumped and as they passed, the smaller polar bear yelled to the larger one "RADIO!".
