Heh, this thread gave me a good laugh (and a nice break from the emo-fest in these forums and all the anti-Nick propaganda. They will air when they'll air, jeez).
Anyway, I dont think it's necessary to add a caption or comment as in some cases it just ruins it and makes it less hilarious than if it would stand on its own ( like The Thing and Toph comparison).
Unless you have something funny to say (i.e KUNG FU ACTION JESUS)
