Years and years ago, I was in an ice cream shoppe and saw two English tourists. The wife was about 6’ tall and built like a barrel with a large afro. Her husband was 5’, with greasy hair and a handlebar mustache and tattoos all over his arms.
She got a waffle cone and was impressed with the size, turned to her husband and said (in a Monty Python woman’s voice–like the mother in Life of Brian)…
The line which I think is the punch line to a joke, but I’m not sure, is “Just hold the tail, I’m fucking this cat”.
Usually abbreviated to “Just hold the tail…”
It’s used in my family when someone is offering unwanted or unneeded advice, like back seat driving.
I always say this when someone says something stupid like, “I like to watch football in my underwear,” or whatever, when you haven’t asked. It’s from “Psycho,” when Marion’s eating the sandwich and Norman says he likes taxidermy. Heh heh…
