The Adventure of Gassy Buddy

I hope this is not offensive to you...but, in my family, we get a chuckle out of "bathroom talk". I don't know why it's so funny, but my sister and I can really get hysterical when it comes to bodily functions. So, you can imagine I enjoyed Maddox's latest observation.

Maddox: I smell something stinky. Who did that toot?
Me: Not me. Maybe Buddy?
Maddox: Oh yeah, you're right. Well, I guess it's another adventure for Gassy Buddy today.

Where does he come up with this stuff????
