It would seem many people feel the phrase and I cannot be overused and choosing it instead of and me helps them to appear both more educated and more eloquent.
This is absolutely incorrect.
When I was in elementary school (and I cry to think that this must not be taught any longer) I learned to break down the group to determine which ending would be appropriate. For example, They wanted to take Shelly and I out for dinner. Break this up: They wanted to take Shelly out for dinner. and They wanted to take me out for dinner. The appropriate choice is and me. This method works in nearly every situation (though probably not all of them since this is English we’re talking about here) but if you’re not sure, rewrite the sentence to avoid choosing all together. Safe not sorry, amirite?
Stop using and I incorrectly. You sound like a jackass (and a poorly educated one to boot).
