Another random thought

This morning’s shower left me clean and with the following thought:

me: How do blind people clean up the poop of their aid dogs?
Robert: How?
me: I have no idea. I was wondering.
Robert: I thought it was a joke!
me: It should be! If you have a punchline, let me know.
I mean, does the dog bark a warmer/colder warning?
Whimper: Colder
Bark: warmer?
Robert: Ha!
