Onset Puns

Previously it would've a curd to me.

I bet it's early-onset Alzheimer's.

The wife and I were discussing how well our son was doing with learning his vowels.

Me: I've heard him say A, E, and I, now he just needs to get O and U.

Wife: He's also saying Y, have you heard him say that yet?

Me: Sometimes.

I guess it's the onset of many paws.
