The art of jacking on is a much unknown art lost long ago in the Roman empire
Archieologists have discovered several requirements for jacking on by studying scripts from roman murals
the requirements are as follows
1.Strong left leg
2.Slightly short middle fingers
3.a high pain thershold
4.6 foot 2.5
we would ask anyone with these qualitys to ontact their local museum and ask about the phenomenon and then ask were they can go for testing into these qualitys in relationship to curent reasearch
"Oh man last night i had the biggest jack on last night and I nearly broke my left leg as it wasnt strong enough"
"That totally sucks!"
