Bisphenol A was walking down the street when he met a MIP

BPA: Hi MIP!

MIP: Hello bisphenol A, lovely day isn't it?

BPA: Yes it is, goodbye!

A bit further down the road he met a NIP

BPA: Hello NIP!

NIP: Uh?

BPA: It's me, bisphenol A, the most commonly imprinted template!

NIP: Sorry mate, I didn't recognize you!
