Montezuma's Revenge

Must stay close to the WC
Montezuma is laughing hysterically
Thoroughly enjoying his revenge at my expense
Didn't drink the water but it made no difference
Been back home for almost a week now
No relief in sight
Getting skinnier by the minute
Looking kind of emaciated and if you believe that
Go some gorgeous swamp land in Florida for ya
I'm sure you'll be interested in
Can afford to starve myself for a couple of weeks
And the word, “emaciated” still wouldn't apply
I imagine Senior Montezuma is getting a big kick out of it
Kind of a sick sense of humour I would say!
