Don't play dumb with me

[Neapolitan Ice Cream]

You're not as good at it as I am...

 

[lynxstch]

Maybe not, but I'm better at everything else!

I use to say to my wife "Don't lie to me, I'm not an idiot."
She replied once "I'll stop lying to you if you promise to as well."

Don't play dumb with me​

No need to play dumb since it comes naturally for me. 75 years next week and you'll never catch up.
