I’m sorry, but there was a comic in the early 70’s call “Filthy Richie.” He had a distinctive hair style with “horns.” Now look at the dark figure between the trees behind Calvin. This could get “dark” real quick.
What is a “TWIN”? It is when there is more than one progeny born at the same time. How many animals in that park give birth to only one at a time? Frogs give birth to hundreds, Bears give birth to 2, 3 or 4. I won’t get into insects. Basically, our little friend is reminding him that there are very few “singles” born in the park. – Glad I could help. :-)
Okay… Is Jimbo doing his best Captain Morgan impression with lumber?
