An interesting phenomenon is the often seen confusion of nominative and accusative/dative. Native speakers of English are sometimes not aware anymore of this difference and say things like “for you and I” – probably because they were told at school that “me” should not be used for the first person singular. So now they don’t use it ... Even if it is the only correct form. Saying “for you and I” is the same as saying “give the apple to I”. Not even the biggest moron would say that. Examples of correct usage: You and I should have a word with one another (nominative). Nobody has heard of you and me (dative). For you and me this should be no problem (accusative). Another very common mistake in American speech is the question “where are you at?” instead of “where are you?”. This would only be correct, if one could say “at where are you?” – but one cannot.
