While the wide-hiped, dragon professor was doing a presentation, you asked if you could go to the bathroom, he said yes, so you went. During his presentation, he suddenly felt gassy...

"One moment I definitely NGHH... have a call to take..."

He says, while clencing as he runs out of the classroom and while in the hallway, he sees you.

"Oh hey there... Awkward time..."

He says, as he lets out a fart.
