My son had the teacher asking what words they could come up with starting with B. My son said "B is for Beetle".

The teacher started drawing a garden beetle with legs. My son promptly corrected him that a Beetle has 4 wheels, and he should not be drawing one with legs. "B is for Beetle car, not beetle insect"

Not bad for a 5 year old.

Good to see that your lad is giving the teacher a proper education.

It was when the letter D was being discussed, and words like dog, dinosaur, door were being thrown around, and my son said "D is for dodecagon"

The teacher was stumped. All he needed was a 50 cent piece.
