There's a Presbyterian Lord's Prayer and a Protestant Lord's Prayer? How do they differ?

I know about the variance between the way Catholics say it and the Protestant version (Catholic "who art" and "for thine be the Kingdom etc" is a separate prayer, and we generally call it "The Our Father" rather than "The Lord's Prayer"), but I didn't know Presbyteriamns said it differently from other Protestants.

Of course that kind of thing could make joint acts of worship tricky, even among a mixed bag of Christians.

How about "Please God, let's have a good game today", and leave it at that?
