Put stuff in your mouth - The PERFECT way to hide evidence!

[Winklabom]

This idea is like the long-ago suggestion that spacemen should be able to hide things in their butts. except not terrible.
I fully support this welcome alternative (only in ss13 would butt-smuggling be suggested FIRST) and I like the possibly negative (rarely positive?) consequences that could be scripted in for certain objects.
I now want to store an armed mousetrap flashbomb in my mouth.
