Old Russian joke

A young guy is drafted into the army, he pleads to the Chief Enlistment Officer:

Conscript - I beg you, tell them I'm unfit for duty and I'l give you $1000!

Officer - You're not lying to me are you? Alright, meet me at the cemetery at 2AM with the money.

The conscript arrives the cemetery precisely at 2AM and sees the officer standing on one leg on top of a grave, the officer is naked, playing a guitar and singing songs. He sees the conscript, gets off the grave, takes his money and tells him: Tomorrow at 10 AM come to the draft committee and I will make sure you won't be drafted.

The following day the conscript stands in front the draft committee:

Officer - You're now enlisted in the navy for 2 years! The conscript almost has a heart attack.

Conscript - How could this be? Last night I met the chief enlistment officer and gave him $1000, you can't draft me!

Officer - This is slander! You didn't give me anything!

Conscript - I did! You were naked, standing on one leg on top of a grave in the cemetery, singing songs all night and playing the guitar!

Officer - Comrades and members of the committee, it's obvious this man is insane! We can't enlist him in the navy, he has to be forbidden to join the military!
