Heh.. me and my dad put one of those remote-controlled fart machines under my Mom's chair before we ate dinner. She cooked up a nice dinner for the family and then sat down to say grace.. and then during the middle of the prayer, I hit the button and *RRrrrriiip*
lol, we all burst out into laughter and my mom turned red, she said "What is that?!?" and my sister said "It was you mom, you broke wind" Then she got up trying to look for it, and bent over to look under her chair when I hit it again *Rrrrippp* .. rofl, it was great.
Oh yeah, this morning before leaving for school, I emptied out the sugar bowl and filled it up with salt... Then when my dad came downstairs to eat his cheerios, he was like "What the hell, this taste like ocean water..."
