Also from billr (and travelgirl):
Is it because his ears are covered by his costume? He can’t hear anything on his phone?
Indeed. My other question is where he puts that phone when he’s out webslingin’! Not really sure I want to know…
Telephone call for Peter Parker
Comics I Don't Understand 
Because of his “spidey sense” he knows it is a marketer calling.
I think McLeigh has it. His spider-sense warns him of danger. Otherwise it’s a baffler.
When I read the comics ages ago, Spider-Man would carry a camera for his other job as newspaper photographer. He’d web it in a corner somewhere where it could catch all the action during the big fight. I guess his spider-sense told him the best place to put it.
Nah, his Spider-Sense didn’t help with camera placement other than warning him if someone was watching him do it. At least once he was criticized for poor quality and framing of his pictures.
As for where the camera goes, artistic license…he actually has a belt under the suit with stuff like camera, spare webbing, etc. The belt and the wrist units of his webshooters simply don’t get shown through the cloth of the suit.
The squiggly lines show that his Spider-sense is warning him of danger. So mcleigh has it.
That’s essentially me nearly every time my phone rings. Thank goodness for caller ID. Bloody telemarketers and scammers.
Oh yes, mcleigh nailed it.
Spiderman used to set up his cameras on roofs where he expected action. I think he gave up on the whole photography business.
One of the last Spiderman newspaper comics had him doing something in front of a crowd. Jameson asked them “Did anyone get a picture?” and a multitude waved their phones at him.
Some years back picked up a paperback collection of “Spidergirl”. In the near future, Peter Parker lost a leg and abandoned (but never revealed) his Spiderman identity, settling down with Mary Jane. He became a police scientist, as he was always a science nerd and photography was only a means of monetizing his superhero-ing. All’s well until teenage daughter develops superpowers …
If Peter hadn’t be doing the superhero thing, he’d likely have made a lot of money just with the invention of the web fluid.
@bensondonald: So Spider-Man passed on an acquired trait to his daughter?
(Not the first time. Canonically, Plastic Man became Plastic Man after being dumped in a vat of chemicals. In the 1980’s TV cartoons, he was married and had a plastic child, Baby Plas.)

That actually came up in the comics a time or two. Parker tried to sell the stuff to chemical companies, but they weren’t interested in a super-adhesive that dissolved in a very short time.
Gnoman (10): That sounds like a great thing for surgeons (or their assistants).
Also every two-bit villain with tinker abilities can recreate web fluid when the plot wants them to – as have a number of heroes and random scientists – so it’s not like Dupont couldn’t just figure it out and patent it. Heck, in the movies Tony Stark whipped it up for the mechanical suit so easily he didn’t even mention it.
Peter Parker used to be one of the top two or three scientist-engineers in the world but comic power creep has made him below-average. Now he falls somewhere between Paste-Pot Pete and Squirrel Girl in technical ability.
