Had a good punchline.
This flash definately made me laugh. I thought the animation was good, and the joke was so ridiculous that I couldn't help but to find it funny. Did you attempt to sound like Strawberry Clock in your normal voice, if so, it simply added to the humor. It could have used a background of somesort, but I understand that it is Clock Day and simplicity gets the best of us, so I'll let it slide.
Even though it was on the bland side, the laughs really pulled through and made this animation a lot better. Maybe Pikachu's mouth could have at least moved or you could have thrown a few more jokes in there, but the one you included was pretty clever. Anyway, I appreciate all the laughs this gave me, have a good Clock Day, and keep up the good work!
