I know you really, really want to come up with an ad slogan that will catch on with the public just like "Whazzup!" did. But I'm sorry to let you know that, "Here we go!", isn't it.
No matter how many times you repeat "Here we go!" in any single ad, and no matter how long you keep airing these "Here we go!" ads, it won't change anything. If "Here we go!" hasn't caught on by now (and it hasn't), it's not going to catch on.
My suggestion: go back to the lizards and frogs.
Here are 6-1/2 minutes of them all together.
