Favorite cameo?

I've noticed that in lots of older Marvel comics we'll often see Spider-Man or one of supporting cast in a non Spider-Man book.

What are your favorite cameos?

I'd say mine would be in Fantastic Four with Aunt May. Can't remember the issue number. Doom was apparently killed in the issue.

2nd favorite would be when Jameson yelled at Godzilla. Also Spidey swung by taking pictures of Godzilla leaving New York.

The Doom cameo was in [I]Fantastic Four [/I]#260, I believe. That was a great story.

My favorite may be J. Jonah Jameson in [I]Fantastic Four[/I] #50, when he convinces the public that the Fantastic Four's greatest triumph: saving the Earth from Galactus, was a hoax.
