I'm usually not one to pick up on grammar, but I like to pick people up on this one because it's usually an example of people being pretentious, yet getting it wrong. I always say "me and my wife", because in the town where I grew up, to say "my wife and I" would be pretentious. But when people say "for my wife and I" it goes through me. It's double reverse grammar pretention.
