55 - Mai Tai on the Rocks Please (S4, Ep10)
We watch "Midnight" (Season 4, Episode 10) where the Doctor goes on an educational tour whilst Donna wisely sits this one out to get a Brazilian. So on the titular resort planet, high radiation and lack of hospitable atmosphere doesn't stop the Doctor from having fun with a small group of small minded travelers who want nothing more than to kill each other at the first sign of trouble. Sounds like my last trip to the Wisconsin Dells to see the Tommy Bartlett Water Show. Oh the humanity.
