so i was reading up on the flavortown man himself

guy fieri (pic related)
but then i started wondering, what is his full name? is it actually guy fieri? is his first name guy, last name fieri? was he born just as "guy"? is what what his friends called him? his parents? his wife? does he have a middle name? guy "flavortown" fieri? or is it one of those band celebrity names where his real name is still out there, somewhere...
uh does someone have the answer
