Here's a strange pairing. I was seeing if Vader ever fought Lex Luger for whatever reason and came across them teaming from what I think is late 1990:
This is actually kind of a cool superteam, but the image of Vader high fiving a face Luger at the end is tough to stomach.
I don't recall seeing Vader there around that time. I remember he was in for the match with Hansen at Wrestlewar 91, so maybe this was transitioning from the Luger feud to the Vader one for Stan?
