Years ago, probably 2012, someone posted a screenshot of Timmy Turner as a reaction image. He was sitting down and grinning at the viewer and his mouth was enormous, doubling the size of his head, nothing but teeth.
I don't know why but it made me laugh so hard I cried and I linked it to a friend who loved it also. But neither of us saved it. We still talk about it to this day. I have considered watching the entire series just to find this one frame.
Please lord Jesus tell me someone has it. I'm pretty sure it had a 4chan filename so it must have been posted more than once.
