Well, as the title suggests, this has something to do with closets. 

These kids that were in my class last year decided the closet looked like a good place to hide. And, of course, these were the two kids that everyone joked were gay together (one of them was dating a girl at the time but it was still a joke) so when they got in the closet together, you can imagine what the class said.

 "They're gonna make out!"

 Next thing ya know, just because someone said something about it, one of the boys started making smoochy noises like they were making out. 

At that point, our teacher said, "Ok boys. Get out of the closet." 

 They opened the door and got out. 

Didn't get stuck this time. 

And, yes, they've gotten stuck in the closet before... There were three guys that time...
