I like to crack my neck because it gives the impression I'm a tough, menacing brute. People respect a neck cracker, because they think, "my god! If he's willing to snap his own neck like that, what might he do to me?"

What won't I do is the question! I'm crazy, and you best respect that! Now, get me my Slurpee!

Cracking is an attention getter too. I'm like a peacock fanning my tail feathers, showing off. My feathers however are tattooed with the message, "I'll punch you in your face." Cracking is a threatening plume!
