We're assuming that this guy was attempting to take an underwater selfie.
He does not approve.
His night vision is perfect for interrupting hipster photo shoots.
He stood on that pinecone to get in this photo: commitment.
"Sorry, did I ruin your postcard?"
Still part of the family.
Maybe planned, still terrific.

"I'm part of the family too. Why shouldn't I be in the picture?"
"Another animal is getting more attention than me!"
Maybe this was planned?
"Oh, you were taking a picture?"
Just a man, a woman, and their horse.
Even dogs can enjoy 3D.
The photographer is holding a steak.
This donkey has a place to go.
Quick window bomb before flying away.
Just gonna sneak in here.
Cool boat, dude.
Pretty scenic, huh?
Bet he didn't see that coming.
Is this cute or just incredibly creepy?
Nope, FCC cat doesn't approve of this.
Get a room.
He knew what he was doing.
Sweet picture, dude.
This probably ended well.
Don't get out of the car.
That couch looks pretty comfy.
Dude, pipe down over there.
What's he planning?
When you gotta go, you gotta go.
Up close and personal.
You're never too young to get photobombed.
C'mon, ditch the girl and come play with this ball.
Not just any goat bomb, but a sarcastic goat bomb.
