The so-called "professional sport" - but really just a lucrative hobby - that does not require any sort of physical fitness. Many who play are known to cheat by juicing, which leads to the ridiculous paradox of overly muscular guys covered by a layer of blubber. Often these players' heads are disproportionately big, rendering bobbleheads rather lifelike. Some defend the hobby by pointing out its cerebral strategic aspects and comparing it to chess, ignoring of course that unlike obeseball, chess players are often in decent shape and don't require other people to decide their every move.
