A mumm about squirrels reminded me of this.
One of the funniest things I've ever witnessed.
My old house had this garden wall adjoining 4 neighbouring gardens.
We'd thrown out a load of seeds and stuff for the squirrels.
This one squirrel was sitting on said wall munching away, and another was staring at it from the other end of the wall.
This second squirrel proceeded to sprint full length down the wall, head butt squirrel #1 up the arse in to the neighbour's garden, and steal it's seeds.
Man oh man was that hilarious.
