Case #4589765 in the 'My Parents Are Traumatizing Files'

Out at dinner for my mom's birthday tonight:

Brother: *has Sunday with cherries on top*
Me: Ooo. *steals cherry*
Me: Can you tie the stem in a knot with your tongue? I can never manage it.
Brother: Nope.
Mom: Nope.
Dad: Yep.
Mom: You can?
Dad: Duh.
Mom: If you can do that with your tongue-
Me: For the love of God, stop that sentence right there.
Mom: -then why can't you-
Me & Brother: AHHHHHHHHHHHHHH! STOP PLEASE STOP!
Mom: *whispers something in Dad's ear*
Me & Brother: *are so scarred*

And now back to paper-writing...
