Paul and Max come in a hospital room to a guy with cast around his leg in the bed.
Paul: Hi Tom! We've been hitting some great bars last night. Have you been to any bars recently?
Tom: Very funny. I've been in this bed for weeks!
Paul: How's your movability? Cholesterol? Overall fitness?
Tom, pointing at his leg in a cast: Movability with cast is zero. Cholesterol could be better, I guess.
Max: All fine here!
Paul: That concludes the study. People who go to bars are healthier than those who stay in bed.
Tom reaches under the bed: Where is the bedpan? You'll stay in bed, too...
Max: No stress! Just go for a beer...
