Hey guys, it's Peter once again in your Wait, Wait, Wait, Feed.

I am so pleased to present to you another episode of How to do everything by wait, weight, weight producers, Ian and Mike. On this week's show, they actually answer a question that we've all had, but have had trouble articulating, namely, how do you talk to the dentist when your mouth is filled with

subscribe to how to do everything at their own feed.

Thanks.

rescue rats who can actually go in and navigate these tight spaces that other technologies can't

reach and also locate and identify human survivors. Wow. How do the rats tell you that? How do they

give you that information? Yes, so we've trained them to

pull a microswitch on their vest whenever they are in proximity of a human. And they pull a microswitch

and it triggers a beep back to our base point, our base camp that they've found someone. Okay, so I should be

picturing these rats wearing vests.
