He has a calculator he likes to play with lately.
This morning he had a brainstorm-
"Dada! I want you to SWING ME LIKE A MONKEY while I calculate!"
'Swinging like a monkey' is when I grab him by the feet, hoist him upside down and carry him around the house to a soundtrack of primitive grunts and hoots. So I hefted him up and walked down the hall while he very intently plied the keypad.
We arrived in the bedroom and I set him down.
"Uh, Dada? Think I calculated the BIGGEST NUMBER EVER. See?" Holding out the calculator for my inspection.
"I think you did, Fuss!"
