Well, I get where you're coming from, but I'm not sure this scene could really be described as him being actively involved in any action. He just kinda stumbles around looking surprised at everything, acts clumsy, then climbs into a fridge. The 'best' part of his involvement in the scene is thinking to get in the fridge. Of course, in a world that even remotely follows the basic laws of physics, it wouldn't have done him any good. If I buy him saving himself from a nuke in a fridge, I'd just as easily buy him using chewing gum to make a baloon that could carry the weight of a jeep gently down into water instead of having to use a rubber band CGI tree later in the movie.
In the end, I guess it depends what we're trying to achieve here and what perspective we're looking at it from. I want a version of the movie that sits well with the others, which means it can have fantastical and improbable escapes ... but not OBVIOUSLY impossible ones. If you jump out of a plane in a rubber life raft, you'll probably die ... but if you keep a good angle to slow decent and land on a major slope covered in cushy snow then I can suspend my disbelief and accept that maybe, just maybe, if all the planets are properly aligned, you could do it and walk away. I can't say the same for the nuked fridge. You'd be dead. If the initial concussion didn't turn your brain to jelly, I say you'd get enough radiation exposure to die anyway. And if that didn't kill you, the concussion of landing would kill you. And if that didn't, your proximity to the blast while outside of the fridge would expose you to enough radiation to kill you.
Now if it's just that last one, I can tell myself maybe he'd be alright ... maybe he was further than he seemed to be ... maybe with a good scrub down he'd walk away, which is why I left it in. But when it's 4 ways to meet certain death in quick succession, I just can't buy him walking away. So, for me, having a version that sits beside the others means nothing so extremely beyond the events of Temple of Doom or Last Crusade (in either silliness or stupidity) that it appears to take place in an entirely different universe.
That would essentially be my case for leaving out the nuked fridge.
