The ends of lines
Are grouped by rhymes;
Within each pair,
Two treatments shared.
If something lurks,
This plan still works,
But it takes time
To match the lines

An instructor trying to decide how to offer a course
borrowed a strategy from randomized experiments:
heads for face-to-face mode, tails for online.
Now she has a flipped classroom.
My roommate and I argued about what to do,

heads we play Monopoly, tails we play poker.
The coin toss was a game changer.
