Escalator trolls

Just had to mention what a great illustration accompanies this article: https://www.straightdope.com/columns/read/779/why-are-there-green-lights-under-escalators/

That would make a cool T-shirt!

Escalator Trolls would make a great band name.

This reminds me of the time my daughter and I were standing in the checkout line of a small grocery store with a squeaky conveyer belt. We tried to talk to the cashier about how the enslaved treadmill ducks were complaining and had she no feelings for the suffering of waterfowl condemned to labor in darkness? But she just gave us a blank humorless stare. It was a saddening experience.

How do you think the ducks felt?

I like to think that late one night when the place was closed they made a break for the river.
