Vance and Vaughn have begun having conversations. They're very one-sided, but they're still conversations and are extremely funny to listen to.
Vance: "Vaughn, are you setting dinosaur traps?"
Vance: "Vaughn, what kind of dinos are you trying to catch? Troodons? Vaughn, say troodon."
Vance: "Good job, sweetie! You said troodon! Mom, Vaughn just said troodon!"
Me: "Yes, I heard. Good job Vaughnie."
Vance: "Vaughn, do you know that troodons are the smartest dinosaur? Say right."
And it keeps going like that all day long.
