It depends on the size of the point of the instrument doing the puncturing (i.e. a needle takes only a little force, but a bullet takes quite a bit). What you really need is how much pressure does it take to puncture skin. I don't believe there is a tested exact amount of pressure required to pierce human skin. One theoretical number taken from the paper linked below is:
(3.183 x10^6 Pa)this is bull **** the femur can't take that much its is really 20000Pa 461.7 PSI (Pounds per square inch)

It would be hard but not impossible, however a great deal of force would need to be applied and that kind of force is unlikely to be able to come from the average human. By the way why would you ask that?
Based on the results of a study published in the Journal of Neurosurgery: Pediatrics our skulls need 520 pounds of force on average to be crushed. The average adult male has 200 pounds of potential force. Therefore, you would have to be one super strong beast of a man to be able to crush someone's skull with your bare hands.
The average human tongue is 4 inches long.
The percentage of flesh in the average human body according to my calculations should be 35,74429%
The average human body produces one quart of saliva per day.
It's possible if the BB gun fires with enough force.
you have to put your hand in a toilet and lick it... i try it...it works
Yes it is possible
The average person is about to do a force equivalent to 150 pounds using both arms. This will of course vary with the person.
Go to the aquarium and see
At least 15 miles per hr
Yes. 35 pounds is a force that is well below what most humans are capable.
Carnassial teeth often cause puncture wounds when a cat bites a human.
Depends on your school, the terms in which you pay it back. Average student debt load is $25k.
46 chromosomes are needed to create a human
they both are used to take in, puncture, and chew up prey.
As the mass of a human body increases, so does the g-force exhibited on the human body.
