Best. Photobomb. Ever.

When Joshua Bass posed for his third-grade school picture, he thought it would be just another yearbook photo– little did he know that a very special someone was sneaking into the shot behind him.

After Joshua said "cheese," the photographer gave him a chance to see the photo–which showed his prankster dad in the background. After a few seconds of confusion over his father's apparition on the camera's screen, the photographer remarked with a chuckle that the boy should turn around.

Army Corporeal James Bass had made the school his first stop after returning from being stationed overseas in Kuwait for a little less than a year.

Check out the video above, to see how Father's Day came early for this little cutie.
