How people smuggle things through security

I have to admit, these people are ridiculously clever.

About the snake... We don't need anymore, thankyou very much; we're managing well enough without spares.

Or put the money in your wallet/bag

Could someone explain the crayon one? Thanks in advance :)

The first one though.. That's a lot of dough.

Last one showed some extreme vigilance from the guards.

Before body scanners, I smuggled my pet hamster through security by having him hide in a shirt pocket. Transferred him over to a little portable cage/box in my backpack. Easy peasy.

It missed the one about smuggling drugs or money inside one's body, or genital..
