This reminds me of the Two Ronnies sketch where they used letters and numbers instead of words. The skit took place in a restaurant and the characters spoke with heavy accents. As I remember it, it kind of went like, Customer: LO (hello)
Waiter: LO
Customer: F (have) U (you) NE (any) X (eggs)
Waiter: S V F X
Customer: F U NE M
Waiter: S V F M
Customer: N T
Waiter: S V F T
Customer: I 1 M N X N T
Waiter: M N X N T 4 1
Customer: S
It was quite a bit longer but memory fails you get the idea though. It was very funny. Den
