Was just playing Subspace Emissary, I picked up a CD (Mike's Theme), then had Ike join me in Subspace.
Then when I end the game, I get zapped to the challenges screen, and I get the messages;
"You got Mike's Theme!"
"You got Ike's Theme!"
And I was like "WHOOO I GOT MIKE AND IKE'S THEME" and my friends were staring at me weirdly and then I laughed
....god I'm easily amused. XD
