I May be Pathetic, but what can I do?

So the other day I was bored at work, so I took one of my coworkers wireless phone headsets and switched with another coworkers. I laughed a lot when she tried to answer her phone, but could not pick up the line. I know, I know. It is pathetic how little things like that make me laugh, but they do. I can't help it, the "what is wrong with this phone, I don't get it" sent me over the edge. Do I need help? Can you even get help for problems like that?
