Wife and I's

Today I was ordering checks from my bank, and I asked the telephone representative, "Can you get rid of my wife and I's middle initials from the checks?"  I don' think this is proper grammar.  Can you tell me how I should say a sentence like this?  Thanks!

I would say like "Can you get rid of the middle initials of my wife's and mine from the checks?" or "Can you get rid of my wife's middle initial and mine from the checks?"

How about-- Can you get rid of my wifes' name from the account?

 

I don't blame you MrP.  I composed it rather mechanically--

Mr Pedantic and Mr Micawber's new girlfriends.  (We have the same new girlfriends; they are two-timing-- or four-timing-- us.)  As opposed to Mr Pedantic's and Mr Micawber's new girlfriends (separate but undoubtedly equal).

So I extended that to the pronoun.  But honestly, I cannot 'hear' these forms clearly.  Now:

He and my new girlfriend?  No, decidedly not.  It must be his and my, even with just the one trollop, eh?

I'll let you finish this off-- please correct any other inconsistencies.  I am mid-class.

How about "can you remove our middle initials"?  (Of course I realize this is not always an option, but in this case it seems the simplest choice.)
