hehehehehe, reminds me of this one

three elderly gentlemen friends are chatting

the 1st says he is having trouble with constipation

his mate replies No problem there regular as clock work every 7am

the 2nd man says I get annoyed when I go for pee and nothing comes out, stay they for ages sometimes

his mate replies to him No problem there, regular every morning around 7.30am piss like a racehorse

His two mates comment on how healthy their friend is

He replies that unfortunately he does not wake up until 8AM!!!!!!!
