Not bad. If you still have the file available, can you make a DV or uncompressed or something better than mpeg2? Mpeg2 is pure crap for anything but when it's actually on a DVD... and even then it's crap as far as I'm concerned ^^ One other thing you could do is actually key it out and render as a targa sequence with alpha. Any decent editing software will import that just fine. The Energizer logo is fine as well, that's just some easy masking to remove it.
I randomly looked up running gag on Youtube, and one thing that came up was the scene from Monty Python and the Holy Grail where Lancelot is constantly running toward the camera. I'm not entirely sure how it could be used, but I figured I'd mention it in case it gives anyone an idea, go ahead and post if it does. And also I encourage everyone to look up 'running gag' on youtube and just look around a bit. Consider what you see in terms of what worked with Geico Money and what you see and maybe we might get some last-minute inspiration.
Edit:
All right, I looked at one of my favorite things, Youtube poops, to get some ideas, and remembered one of my favorites. And it gave me some potential ideas.
http://www.youtube.com/watch?v=hGRKpQ7YpH4FIRST: The part I'm talking about starts around 2:20 with the explosions. I actually used this audio for my Gundam Wing one in AMVS3, but I don't think it'd be bad to re-use it. I think this could be a really really fun running gag, and relatively simple. Basically choose scenes that surreptitiously involve someone clicking something or stepping somewhere and then we choose a really funny explosion. The audio from that movie I think has great timing and impact. I'd prefer not to use the "WTF *BOOOOM*" since it's overdone, but it could be used ironically. This one I think could really work well for some good slapstick running gag comedy, and it has all the elements of what the Geico Money had. Even if the explosion changed, we could use the same sound effect and it unifies the audio.
SECOND: The other thing I thought of is, as it appears in this youtube poop, is Bell Air. We could Bell Air various anime. It doesn't have to be done more than a few times, but it'd be like Head On. And like Head On, we could do variants on it to have even anime characters get angry at it. I had Excel shot in the head with head on, and there was also the Big O one where it couldn't get through with the record scratch. We could do similar things. I've seen it work before where you have a serious scene going on for a bit and the character goes "But then... then I got scared - cut - And said yer movin' with yah auntie and uncle in Bell Air!" We could even choose a certain anime character as the one who sings Bell Air if a good one were chosen.
I personally think the explosion idea could be a strong one. It's very simple, slapstick, looney toonsish comedy that offers a wide range of possibilities, and also a wide range of footage. Like I could already see a scene of a shoujo anime where a girl gives another one a gift and she rips the wrapping and a building explodes or something. Or Spike in Cowboy Bebop going off for a mission, flips a switch in his little fighter and another explosion. Like Geico Money, we can have long and short build-ups to mix it up.
