There were 3 guys that was sentenced

There were 3 guys that was sentenced to 5 years in prison under solitary confinement. Feeling sorry for them, the warden allows them a request each.

The first guy, a glutton, asks for 5 year worth of junk food.

The second guy, an alcoholic, asks for 5 years worth of hard liquor.

The third guy, a heavy smoker, asks for 5 years worth of cigarettes.

Their requests were granted and they began their sentence.

At the end of 5 years, when they are due to be released they found that, the first guy had died possibly due to eating too much.

They open the second door and also found the guy dead due to alcohol poisoning.
