Trying to remember my cousin's Marvel Comic

I remember my cousin had a comic that was a Fantastic Four and Spider-Man crossover.

Peter got on a train or bus with Mary Jane....and the Fantastic Four happened to be on the same train. I think Peter and MJ were married, but Reed and Sue definitely were because their son was there.

The Thing amused their son by mixing up stories of himself and Spidey. I know one in particular had a clothing truck fall on the Thing and Spidey and Peter came up wearing women's clothes - a hat and sundress, I think.

Can someone help me out?

Can you narrow down what year it might have been? When did you read it?

I was so young, it must have been years ago. There's no way I can remember what year...but I'm 17 now and I guess I was about 10....so you can guess about that far back.

I just asked my boyfriend who is all about this kind of stuff. He said he had never read it specifically but that you might be able to find it on this site.

Ok, I wasn't able to find it there, but it helped me in the search nonetheless, thanks. :) As it turns out, it was a promotional comic through both Marvel and Amtrak. I had to manually add it here: http://www.librarything.com/work/14313764/book/102475261

Awesome! Glad you found it! What an oddity of a comic. May I ask how you finally tracked it down?

Well, that website you linked me? It wasn't that helpful for the search itself, but it jogged a few memories. After adding a couple different key words to my search, I was able to find its information through Bing. :) (Yeah, I prefer Bing over Google, lol)

Haha! Well, so does Spider-man if the newest movie is to be believed. :)
