Before Cobra Kai, William Zabka made many appearances as Johnny Lawrence. Mostly for gags.

One being the music video, Sweep The Leg, by No More Kings. In which Zabka plays a washed up mash-up of himself and Lawrence. Seen with his fellow Cobra Kai friends, while he laments his past failure. Only for him to try to put himself back in shape, train in a different style and see if he could beat Daniel/Ralph Macchio at his own game. Only for it to all be a dream and him being ran over by Macchio.

Another being a frequent guest star on How I Met Your Mother. The first of which also had Ralph Macchio. As a running gag, Barney Stinson, believes the villains of every movie are the real heroes. The big example being that he's a huge Darth Vader fan. In this case, he believes that Johnny Lawrence was the True Karate Kid of the story, because he was trained at a legal gym. During a surprise party for him, he was dissappointed that they got Ralph Macchio instead of Zabka, only to his surprise, that Zabka was with him the whole time. Disguised as a clown with his Cobra Kai gi underneath the costume. Making Barney's dream come true look even better since, in his mind, now that both are here, they'll have a rematch.

But my personal favourite of these gag appearance, is the one in 2011. It was a random Sketch on The Jimmy Kimmel Live Show. This was at the time when Ralph Macchio, was a contestant on Dancing With The Stars. Now I seen Ralph dance before. Karate Kid Part II's dance scene with Daniel and Kumiko was no stunt double, that was him and Tamlyn Tomita dancing on that floor. So I knew he'd be an ace on that show even if he doesn't win them all. But what I saw shocked the hell out of me. I don't know how Kimmel and Zabka got the right reactions to show Macchio's shock, but they super imposed Zabka as Johnny going after Ralph despite getting a perfect score.

It makes me wonder has Johnny been stalking Daniel everywhere he goes? Let's find out.

Here he is in Outsiders:

And Again in My Cousin Vinny.

And if Ralph thinks he can hide behind comedic legend Artie Lange in Beer League, he should have wondered if Johnny was a baseball fan.

Seems every where Ralph goes, Johnny Lawrence is ready to strike first, strike hard and show no mercy. Which is what we hope he will do in Season 4's Cobra Kai, which will be coming soon.
