You forget sometimes that comedians and celebrities are real people who are just going about their day like regular people. Like regular people, they have medical check-ups. Ricky Gervais was on the Late Show with Craig Ferguson talking about, amongst other things, being recognised in public.
The conversation lead on to, well, poop and sure enough, Gervais brings up a very funny story about getting a prostate exam.
That's gotta be awkward. Being recognised, not the prostate exam. Those are very serious.
