Now I can say that in Spanish
I was half expecting to see him go up to a female dog and say that, but it was something else. I kind of thought this was some of your lesser work, as it didn't have much of a punchline. What really saves it is how good the animation is. It's funny to just see him jumping around (apparently, you can say, "la la la" in Spanish). It's easy to follow and it helps that there's a lot of setup for the final joke. It may have been predictable, but it isn't terrible at all.
