Without any laughing or headshaking involved...I believe you already know the answer to this question.
IF he should try to strike at you...the worst part of it is simply being startled. It's really no big deal. But chances are pretty unlikely that he'll try. If he was going to try, he would have done so with your hand just hovering in the enclosure.
I really believe you only need to do it once to get over your initial anxiety. Just reach in and gently scoop him up around the middle and lift him out. It'll take all of 3-4 seconds and then your fear will be gone.
One thing you can try beforehand is to picture him striking and biting....and imagine yourself just watching it calmly and not reacting at all...because really, it won't hurt in any real way and he's not being mean, he's just trying to scare you away....and you're so much bigger and stronger than he is. So imagine yourself being completely calm and cool under that scary situation.
Give it a try and let us know how it goes.
