It's All About Marcus

The little guys were in the bath tonight and T2 says: "Look mom, my fingers are wrinkled like an old man, like Marcus." A few minutes later I ask who is the oldest man he knows, to which he replies "Marcus!". I then ask who is the oldest woman he knows, to which he replies "Marcus! Marcus is a woman!" He gives it a little more thought and follows it up with "No, Mary is the oldest woman I know, you know Jesus's mom."
