Public transport rioting

I was on the CTA mass transport train in Chicago and the funniest thing occurred.  The Conductor walked up to me, look at my t-shrit, and said, 'I riot for cacao...what's that?"  I began to explain to him what cacao was and he sampled some and soon some other passengers began rioting too.  Public transportation rioting.  In the mean time, cacao was spilling all over the inside of my suitcase...these things happen sometimes.  Ah, yes, all in a day's work.  :)
