Well, I don't drink these together (yuck!) but I do like both of these beverages. Even though they are BAD BAD BAD for me, they are my "happy place".
On a different note, Mitch loves (did I say "love"?) McDonald's sweet tea, even if he does dilute it a little bit with a tad of unsweet. I, however, love Diet Coke out of a cold can.
Both make a good marriage.
