Squirrels

Note: sort of loses a bit in written form; just imagine it's being said...

Yeah, 'cause you know you wake up in the morning, and your hair is all over the place? Well that's because, in the middle of the night, squirrels break into your room, with combs and moose, and the moose stand guard whilst the squirrels comb your hair into weird shapes, then they all run off, laughing that moose means two things, and can be used in a joke format.
