The shirt is funny but to be serious here for a minute I have to ask why a person that is going to be crucified has to have his own cross. Did they just use them once and then you cannot use it again? If people were crucified on that hill and it was a common practice the hill most likely already had crosses. Besides, the bibble says only 3 were crucified that day.
Imagine death by the electric chair but you have to have a new chair every time. Then rather than take the guy to the chair you make him carry the chair to wherever they are going to use it.
Just sayin.'
If we pull out of the parade... You're a carpenter, right? You're building your own cross!
