Dr. Thomas is the 7th track Mac Miller’s most recent mixtape “Delusional Thomas,” in which he takes on the character of his alter ego, Delusional Thomas. This song, “Dr. Thomas” is Delusional Thomas thinking he is a Doctor, and an aggressive one at that since he’s killing dentists (because they aren’t doctors according to him). Dr. Thomas is produced by Mac Miller under his production alias' name, Larry Fisherman.
