All parents can relate to the joy of going to the doctor for their first ultrasound. Some parents just want to see the progress of the unborn child; some want to see the sex of the baby. What the parents in this video never thought they'd see is their baby waving at them and giving them the middle finger.

LG shows off their new Smart TV in this prank that has soon-to-be parents in the doctors office thinking they're getting to use the latest and greatest ultrasound technology.

On one hand, I can understand the disappointment a parent would feel after finding out it's a prank. But, on the other hand, this is freakin' hilarious.
