Taste it

Youngest sits on the couch. We're watching something or other.

Me: Oh, look at this smudge on my glasses. What is that? (I think somehow my ice cream sandwich got crazy on  me or someone wasn't watching where their Drumstick was going.)

Youngest with that all familiar gleam in his eye: I bet it's bird poop.

Me: Yeah? Why don't you taste it?

Youngest: No. But I'm pretty sure it's bird poop. I can smell it. *giggle*

Me: Well, if it looks like bird poop, smells like bird poo then you should taste it to make sure it tastes like bird poop. Go ahead... taaaste it.

 I would like to thank Cheech and Chong for that bit. Who knew it would come in so handy?
