Amnesia jokes

Patient: "I'm starting to forget things."

Doctor: "Since when have you had this condition?"

Patient: "What condition?"

I had amnesia once... maybe twice.

I was gonna tell a memory loss joke, but I forgot it.

I stole my friend's amnesia medication the other day, he was pretty pissed.

But I reminded him of the age-old mantra: "Forgive and forget!"
