Don't listen to CrashTestDummy, it is very common. In fact I once had my mouth, nose and eyes glued shut. I was then locked in a locker and thrown down 30 flights of stairs where I was left over the remainder of the weekend. I died from my injuries. Luckily after 3 days light duties, atubbigrip and some Ibrufen from the med center I got better.
My younger brother was bullied out of the same Battalion. I called their 'badge' to try and stop the continued bullying to no avail. His discipline became a massive issue, he finally served a sentence in 'the glass house' and was kicked out. Glad it has been brought to the fore.
Ahh, so they didn't actually "glue his eyelids together", at least not intentionally. Reading between the lines, what we have is a group of lads who got a bit bladdered, thought it would be funny to start superglueing things to body parts (dildo to forehead or similar?) and it all went a bit horribly wrong.
