Comments are ridiculous. People believe he is nailed there I guess its possible, btu I didn't jump to that thought right away
I had to scroll through a few pages of comments to find what the hell you were talking about, and it was still only one person saying it. Why are you reading though pages of Youtube comments?
He's not necessarily nailed or glued, but it's definitely a posed scene. A frog is physically incapable of putting itself in that position.
