I guess, I probably need to comment my message, so the joke would be more obvious. After all, most of you, guys, are very unlikely to be familiar with that one.
Here it goes:
A man comes to a proctologist (ass doctor), doc tells him to take off his underwear and to bend down. What he (the doc) sees than is the guys ass looking totally undergroomed. To make it polite, doc asks:
- don't you read newspapers in the toilet (aka restroom)? [meaning: don't you wipe your behind?]
- no doc, I prefer radio instead
This one is very old (like 30 years or so at least)
