Jose Altuve visits 'Tonight Show' after World Series, meets 'Stranger Things' kids

José Altuve must be racking up the frequent flier miles this week. 
On Wednesday, he and the Astros won the World Series for the first time in the team's history -- and celebrated appropriately on the field and in the clubhouse at Dodger Stadium. On Friday, they'll return home to Houston for a parade through the streets of the city.
But New York City was where Altuve found himself on Thursday night, for a guest appearance on "The Tonight Show Starring Jimmy Fallon" -- and Fallon was ready for some fun (and is obviously in-tune with some recent Altuve-related headlines): 

So excited to talk to World Series champ Jose Altuve tonight! @JoseAltuve27, I literally love you!

Also on the program were Finn Wolfhard, Gaten Matarazzo, Caleb McLaughlin and Noah Schnapp from the hit Netflix series "Stranger Things" -- and they all posed with Altuve for a great backstage photo:

Fallon at one point donned a new Astros cap in honor of their World Series title, and Altuve approved of his new look:

Comedian/actor Keegan Michael Key showed up, portraying George Springer in a festive confetti-covered postgame interview skit with Fallon:

No, you're not in the Upside Down -- that all happened.
