David and me or David and I?

Both of these are correct.

David and I went to the show.

John gave the box to David and me.

Both of these are incorrect:

David and me went to the show.

John gave the box to David and I.

AnonymousWhich is correct and why?

Use David and me wherever you would use me alone.
Use David and I wherever you would use I alone.

If you want a really simple rule, you probably won't be wrong too often if you use David and I at the beginning of a sentence or clause and David and me everywhere els

AlpheccaStarsDavid and I went to the show.
John gave the box to David and me.

It's easy to understand.

David and I went to the show.
