Guys who had two runs in WWF and WCW

I'm trying to come up a list of guys who had two separate runs in the WWF and two runs in WCW (counting the NWA too).

Meaning guys who jumped from promotion A to promotion B, then back to A, and finally back to B again.

So far I've come up with Bulldog, Jarrett, Sid, Flair, Rude, and Ricky Steamboat but I'm sure I'm missing a ton of guys who jumped around like that.

Do any others come to mind?

Thanks.
