Dryer buzzer

I guess it's a boy thing, wait a minute, it's a Jennings thing, but Sean gets the biggest giggle out of fart sounds!  See the picture below of Sean playing with the "fart app" on the iPad.  Lol! 
We've been working on having Sean just say "excuse me" when he farts!  That's because he will usually say, "Sean farty!!!"
I can't forget this funny...While in the family room, the dryer buzzed (quite a distance from Sean), and without skipping a beat, Sean says, "excuse you daddy!"  Of course we were proud of Sean's good manners, but even more excited that he heard the sound from such a distance.  Now we must work on discrimination of fart sounds versus the dryer buzzer!
