The only true way to solve this: actually going up to them and measuring for ourselves. ;D
In all seriousness, that is an easy way to do it. But I would volunteer for a select few. Not this chick. :P But a few others, yes. :)
I would imagine it would be after befriending them and gaining their trust first. Not just walking up to them and "I poke your bellybutton". As much as that would happen in a fantasy world.
