Only Fools and Horses....1981

Mike Fisher:
[Del and Rodney are trying to sell Mike a computer] What exactly does that mean?

Del Boy:
Well it means you can... you can... tell him what it means, Rodney. [to Mike] He's taken a course in this, he came top of his class.

Rodney:
Well, in 'layman's' terms it means you can, em, well, you er, you can record all your business deals.

Mike Fisher:
I spend half my life trying to hide my business deals. So the last thing I want is to have 'em all recorded on a floppy bloody disc! I'm not interested. Ask Trigger.

Rodney:
Trigger? With a computer? Do me a favour, he's still struggling with light switches!
