More Comic Relief From the Home Front

Is it so wrong that my brother and I get a huge kick out of my nephew making farting sounds?  Or actually doing it and grabbing his little butt exclaiming, "Oh! My hiney popped!"  We for some reason think bodily functions are hilarious.  A classy people, we are.  My mother is always just shaking her head and telling us, "Don't teach him that!"
The scenario:
Last Thursday night we're sitting around the table after dinner and a conversation about how the word "fart" makes one of my aunts giggle uncontrollably, just like it did my grandmother.  I'm almost positive it was triggered by my brother ripping ass for real and Nico giving his infamous shocked expression.  So my brother just goes with it and yes, he starts making farting noises with his hand.  Like he's ten.  And we laughed and laughed.  I got the brilliant idea to try and videotape it like Nico was the one expelling gas.  It didn't work out quite as planned but the footage I got is priceless.

After all of the trauma this family has been through, we've learned that the stupid little things that make us laugh are what's important.  Even if it's something as crude as a fart joke.
