Question for Americans

[thismaz]

So I was watching Supernatural the other night and noticed how Dean and Sam kept calling their Dad 'Sir'. Is that like the norm in the US? Or does it betray their social background? regional origins? Something else? Is it only sons who would do that, or would daughters also call their Dad 'Sir'. Do they call their Mom 'Marm'?

It sounds so weird and formal and distant to my British ears.

Maybe it's me.... Question for British readers - any of you call your Dad 'Sir'? (You don't have to answer if you are a member of the royal family - we'll just assume you do)

That's what I picked up anyway. I could double check about the region thing because my husband grew up in Lawrence, where we met when going to college, the same town the Winchesters are from.
