Working with Kids: Funnier than Your Job

Today I witnessed a hilarious exchange between a coworker and a kid (I work with kids, it's not a random kid):

Kid: Can I have a cardboard box?
Coworker: What are you going to use it for?
Kid: To make a cardboard bong.
Coworker: To make what???
Kid: A cardboard bong.
Coworker: Like...a bongo drum?
Kid: No, a bong.
Coworker:...I can't handle this situation.

A while later I revisited the topic:

Me: Okay, so tell me again, why do you want the box?
Kid: To make a cardboard thong.
Me: A what?
Kid: A cardboard thong.
Me: Like...a flip flop?
Kid: No, a thong.
Me: I don't know what you're talking about.
Kid: You know, like, on your foot.
Me: Ah, yes, I know exactly what you're talking about.
