"As long as you drink....you won't have worms!"
I may have experienced this, NO LIE!!
To ring in New Year of '86 I went to Cancun with my girlfriend's family. There were 6 of us altogether staying in a nice big beach cabana. Mom & Dad...and big brother & his girlfriend were NOT partiers.
Anyway, my girlfriend and I started drinking tequila at the airport in L.A. and stayed SOAKED the entire trip, man. Somewhere along the way, I won a limbo contest...and they gave me another QUART of tequila (which we did not bring home).
Here's the deal....EVERYONE ELSE on the trip came down with the hershey squirts...Montezuma's Revenge...whatever.....missing a day or two of fun as they tried to figure out whether to sit on it or put their face in it.
My girlfriend and I NEVER got sick...and had a BLAST the entire trip. I always figured no worm, germ or bacteria could survive our tequila-soaked systems.
