Can someone explain what the "joke" is? It's just kind of making a statement, which may or may not be true. Usually with a comic, there is some kind of joke or witty play on words. I mean yeah, some people only ride their bike as a means to exercise, train, and race. I'm not sure where it is written that one must use a bike for those things AND commuting? But still...if this is what qualifies as humor, I'm just not getting it.
