Spongebob Squarepants - Clones!
In the episode of "Dunces and Dragons" when Spongebob and Partrick are screaming to the king "pick me! Pick me!" (or something along the lines of that) they are on the left side of the stair case to the rows of seats along with a blue fish a few rows above them looking at them. On the right side of the stair case there is the same blue fish (I forgot where) with the same expression and doing the same thing! The are clearly the same!
