I am a bit rusty on Harpo facts, but I am positive that Harpo was not born in 1893, as he had stated. I have seen a photocopy of Groucho's birth certificate, which established the fact that he was born in 1890. Since Groucho was definitely born after Harpo, I figured that Harpo was a bit confused about the date he was born. I don't think things like birthdates and ages interested him enough for him to remember the exact year he was born, or the age he was when things happened. Food, however, interested him alot, so he DID remember the cost of everything he loved to eat at Max's Busy Bee!
