Spanish grammar Puns

I was explaining the interesting L-glucose thing I saw on Reddit t'other day to my diabetic father.

Dad: oh, so it's Spanish glucose then?

He thought it was great.

Edit: TIL I am a neckbeard-Yorkshireman with a Dad who literally bats for 't'other side' - for anyone still in the dark,"t'other" is contraction of "the other" commonly heard in NE England; it is commonly used elsewhere as a lighthearted/bucolic affectation.
