Examples

"Che cosa hai mangiato a cena tre sere fa?" "Non ricordo, ma fammi fare mente locale un attimo e mi verrà in mente"

"Where were you last Tuesday at 3:00 p.m.?" "I can't remember just off the top of my head, but let me think back... I got it, I was at the library"
"Dov'eri martedì scorso alle 3 del pomeriggio?" "Così sui due piedi non mi ricordo, ma fammi fare mente locale... Adesso che ci penso, ero in biblioteca"

You promised to help me, and if you cast your mind back, I'm sure you'll recall when and where you did it
Avevi promesso di aiutarmi e, se fai mente locale, vedrai che ti ricorderai dove e quando me l'hai promesso
