Smoker never Dies

Every cigarette you smoke,
decreases your life by 5 minutes.

Sex increases your life by 10 minutes.
So basic theme of equation is that

“A F___ING SMOKER NEVER DIES”

Diagnosis

A girl to doctor: when I smoke cigarette,
I feel very uncomfortable,
On first puff, I put off my shoes.
On second, my socks.
On third, my shirt.

Doctor: take this cigarette and tell me in detail.
