this is my most recent, well I have two.
first one, me and my dad where sitting on the couch and my brother came up and complained about his mouth hurting, and I said, "maybe he has an incest tooth."
and my dad laughed so loud and said," an
incest tooth eh? who'd he get if form your sister?"
I was so confused and he laughed some more and said,"I think you mean
abscess tooth?!!"
and I felt like an idiot.

second one, me my dad and my friend Karis(sweetie_pie09223) were sitting on the couch at about midnight watching a horror film and there was a really intense scene and I was getting really scared(I'm horrible with scary movies, (once I got so scared I started chewing on my sleeve and by the end there was a hole in it) and then my dad yelled "BOO!"
(I was sitting between them by the way) and I screamed so loud I swear you could hear it 5 blocks away.
wow this ended up to be really long XD
