Picture this: Billy Ray Cyrus, twerking.

Miley Cyrus' dad is the latest to come to her defense over her ridiculous, booty-shaking, Robin Thicke-humping VMA performance.

Not only does he stand by it -- he wishes he had done it!

Check out this tweet from Miley, quoting her father:

Now aren't you glad "twerking" wasn't a thing back when "Achy Breaky Heart" was a huge hit back in 1992? We are.

And are you picturing Billy prancing around in a nude-colored bikini, grinding all over Robin Thicke? You probably are now, sorry.

See how more celebs reacted to the performance here and find out who was a fan ... and who was mortified!
