How Common is This?

[sleddergirl]

I went into my reptile room last night to do all the nighttime chores......... and Chester had his front foot stuck on his head, I mean seriously stuck.............he was climbing around using the other three legs. By the time I went into the enclosure to help him, he had gotten it free on his own. It almost looked like he was holding his head from a headache. He seems no worse for the wear and is being a complete a$$hole as usual.........

Have any of you experienced this before
