I saw him first!

River:  Nooo!  I get to say hello to Mr. Hoppy-pants first.  Oh, look--he has a little tail!
Simon:  [Jealousy intensifies.  Tries to sneak under River's chin to say hello too.]
River:  You're gonna knock him over!
Simon:  HI! [Nose-bonks the back of Mr. Hoppy-pants' head making him face-plant.] ...Uh, sorry about that.
