The only thing that the government has not taxed yet is the male penis.
This is due to the fact that 40% of the time it is hanging around unemployed, 30% of the time it is hard up, 20% of the time it is p!ssed off and 10% of the time it is in the hole.
On top of that, it has two dependents and they are both nuts.
Effective January 1st, 2013 the penis will be taxed according to size.
