The 2nd Doctor meets the 11th 

both love the bow tie

arguably the two doctors who are the most similar to each other

Two: "Oh, my word! That is a big one!" Eleven: "Yes. Let's . . um . . not go there." Two: "Well, bow ties are cool." Eleven: "This is the Bow Tie King. It is the king of bow ties!"

You can tell Matt Smith based a lot of 11 on 2.

I can only imagine if they regenerate at the same time they would probably both remove their bow ties

Do one on the 3rd doctor meeting the 12th doctor

Bow ties are cool

Typical. Absolutely Typical
