Recently I have heard people use the expression “jump on the bandwagon” a lot (thanks to the undefeated Kansas City Chiefs).  Literally a bandwagon was a wagon that carried the band in a parade, circus, or other similarly silly event.  Supposedly, the idiom, “to jump on the bandwagon,” was coined in 1848 when Dan Rice, a clown, used his bandwagon to attract attention for his political campaign.  Other politicians saw the attention he was getting and also wanted to “jump on the bandwagon.”

This seems kind of odd to me.  You would think a clown aspiring to be a politician would try to downplay his clownliness.  Not ride around on a wagon blasting clown music.  

Clownliness.
