Do you crack yourself up sometimes?
Several times a day, sometimes even snort.
Usually when I do something utterly stupid like bring in a full trash can that hasn't been emptied yet. Today sucked like that. I got 1⁄2 way.
Yep, Especially when I'm trying not to. Like one time I laughed out Loud at a Funeral! 
At my brothers wedding I was behind my other brothers daughter she was about 5 years old cute as a bugs ear and this god awful stench rose up from her, I looked down as she was looking up and says "i poofed" thats when I lost it just as they were saying "I do"
