Hate to "break it to you". Spider-Man does quip, but not ALL the time. I seem to remember NO QUIPS during the death arc of Gwen Stacy. I seen to remember NO QUIPS during the Death arc of Capt Stacy.
I KNOW, that QUIPS during the final battle with GG in SM1, or Train Battle in SM2, would have ruined the moment completely.
Yes, Peter started out as a kid, geeky, etc... and used the Spidey Personification to come out of that shell, but he has also matured throughout the comics run. IF he had not, the comics would be NOWHERE near as successful as they have been.
And you really think I am "ashamed" of going to see Spider-Man??? Get Real. I am very proud to be a Spidey fan. Period.
And for those that say Spidey should be ALL Groucho Marx, All Cheese, All Dancing (I gotta know what frickin spider-man comis you are reading.. or better yet.. WHAT the hell you're smoking while reading them)

t: that Peter breaks out dancing??? LOL
Let's see:
Death of Uncle Ben (Check.. No darkness there, and PLENTY of Quips... "HEY OLD MAN.. Guess that Car Jacker Revoked your License"...
Death of Gwen Stacy (Check.. No Darkness whatsoever) "Hey Gobby.. YOU KILLED THE ONLY WOMAN I EVER LOVED.. but hey.. Baby You NEVER looked Better"
Death of Capt Stacy (CHECK AGAIN.. NO DARKNESS.. NOPE.. all Carebears and Smurfs dancing here

"Before you die Old Man.. I have this year old parking ticket.. could you do a brother a spare?"
Yep.. Spidey = CareBears and Dancin Ponies.
