My personal favourites include Joseph Ducreux, anything to do with mocking hipsters, Never Gonna Give You Up, (or. "the Rickroll", as the more uncultured internet dwellers amongst us refer to it as) Catch That Man, What Is Love, Philosiraptor, RIIIIIIIIIIIDGE RRRRRAAAAACER, and Nyan Cat - with the bottom spots occupied by the trollface, the anti-joke chicken and the Trololo song.
I liked Vocaloid and PRGuitarman before Nyan Cat.
