Doctor, Doctor.

[supergnome]

A man goes to the doctor with a pain in his bottom . He says "doctor I haven't sat down for weeks due the pain in my bottom"
The doc says " drop your pants and I'll have a look"
After looking the doc says " I've got good news and bad news for you"
The man says "carry on"
The doc says " the good news is it's just a lettuce leaf sticking out"
Man says " so what's the bad news ?"
Doc says " it's just the tip of the iceberg "
