"It's a trap!"

I wear drawstring pajama pants to bed on a regular basis. Sometimes when I get up in the middle of the night to go to the bathroom, the drawstring part becomes tangled and I have a mild moment of panic as I realize that I am trapped in my pants. Fortunately I have always been able to get out before any damage has been done (i.e. being forced to use my Hulk strength to rip my pants off), but does this ever happen to anybody else?
