Yes, sometimes it's actually funny.

Most of us who were raised with any manners at all were taught not to laugh at those who are different. And disability is not often funny. But in this case, you can hardly keep from laughing.

Monster the Cat has a vocal cord condition that makes it sound like he's singing when he yawns, and, well...it's funny! And since he's not suffering at all, you don't have to feel bad laughing. Take a look for yourself.
