- This one sounds like X-Men #143, featuring Kitty

16. A hero and his wife find themselves evicted, just in time for Christmas!

- This is Amazing Spider-Man…#314? I remember the McFarlane cover with Peter & Mary Jane on the curb…

20. Thor – while Eric Masterson possessed the power of Thor; the “grinch” character was stealing toys for homeless children, Thor trys to stop him, then feels bad when he realizes what the monster was trying to do; at the end of the issue he decides not to turn him into the authorities, and Captain America gives Eric a lecture about how he doesn’t trust him and that he needs learn to do the right thing

And that’s ALL! Nothing else rang the slightest bell.

8. Uncanny X-Men #143, the Kitty Pryde “Alien” issue. Fun story.

11. The Jack Knight Starman.

14. Dan Jurgens did about 3 Superman stories with this theme. They should bring that tradition back.

15. The Outsiders #5. Cheesy story, but fun.

16. The Amazing Spider-Man, when Michelline & McFarlane were on the book. Memorable cover.

10. Impulse/Max Mercury. It wasn’t in Bart’s book, but in a DC holiday special issue. Written by Waid and Grayson, if I remember correctly.

18. Hitman…a great story through and through.

5. Incredible Hulk (vs. The Abomination, I think)

8. Uncanny X-Men (Kitty Pryde)

A lot of the other ones seems familiar, too, but I can’t pin them down.
