I Have One For Ya

I was at Disney World this year and found a warning sign before boarding a rollar coaster and i saw a sign that said:

 "Prosthetic limbs must be removed to prevent hazards or loss due to ride forces. Please see an attendant for assistance."  

I mean come on i think if i had one id know to remove it before going on rides in an amusement park if i felt it was gonna come off.
