Because of the nature of my siblings, I decided to play along, and sent in this:
OMG y'all would not BELIEVE my sisters! SERIOUSLY. One time, when we were dead broke and had a baby to feed and clothe, I had this horrible, raging, unbearable toothache, and you know what one of my sisters did? DO YOU?
She gave me a blank check so that I could go to the dentist. A BLANK CHECK! I could fill in any amount needed!
Really, who needs a sister like that?
For some reason I cannot fathom, I was quickly disinvited to participate in Sibling Slam. I'm so ashamed, and hurt.
