31. '90 Miami Dolphins "Can't Touch Us" (1990)
At first, this seems like another shameless song parody by a sports team, but a closer look at "Can't Touch Us" reveals another case of life mimicking art. MC Hammer's rap career crumbled as he went bankrupt and became lyrical cannon fodder. Likewise, the Dolphins remained tame since they released the song and they've made it past the Divisional Playoffs just once since then.
It's worth noting that the song takes a direct shot at the Buffalo Bills. Miami would go on to lose to Buffalo in the AFC Conference finals, and then lose to the Bills two consecutive times in 1992 and 1995. The Dolphins wouldn't actually be able to touch Buffalo in postseason until their 1998 victory in the Wild Card Round.
