Back to my school day, I remember one of my close friend (girl) was so blur and asking us "guys, does you guys' Kukuciao (KKC/Dick) got bone or not?". We were laughing till roll on the floor, this question really made me laugh at her everytime I met her for a whole week long. I guess you girls sure know the answer is NO!. Just try to imagine if KKC really gone bone, then what will happen everytime we guys' KKC get erected?
But just now, I saw an X-ray on a KKC, I don't know whos KKC is that? It really got bone! Somemmore fractured... (picture below).
