Ditto on what Dovii said; I've been bitten pretty much by every pet you can think of (except for like, monkeys, and tigers,etc). Working in petstores for 8 yrs will give you that kind of experience.
The absolute worst bite I received from a reptile was a 4' albino Burmese python. This snake hated every living thing, and it clamped its jaws around my middle & ring finger and then proceeded to coil around my whole hand. It hurt like hell.
Other memorable bites were from a 9' burm (this one didn't even hurt so much as startle me, but it left a few teeth behind), a prehensile-tailed skink, and a fire skink (probably the most painful lizard bite; it clamped down and then death-rolled like a croc).
