Alright, here’s something I’ve been itching to know for a while: what exactly is Pam’s last name? There are no less than three spellings of it out there, all from what could be considered official sources. Eagled-eye viewers will have noticed inconsistencies with Dwight’s last name as well, but we’ll leave that burning question for another day.

We start with the official site first.

This one comes approximately 4:10 into the Sexual Harassment episode.

Finally, we have it straight from the source herself.
I guess the IT guy could have set her name for the email account initially so I think we can discount the "ea" spelling. imdb also has it as "beesley" so my official vote would go for that spelling. Perhaps the NBC web guy just screwed up.
Personally I think it should be spelled 'Halpert' but that's just me :)
To set the record straight, in all the scripts for the show (the only true definitive source), it is spelled Pam Beesly. The NBC website is correct. Dwight's last name is spelled "Schrute."
Perhaps the script writers are just wanting to test our nerdiness factor in noticing such inconsistencies.
You know, I never noticed that before. Interesting question though. i agree, pam halpert would be much easier.
Nice little feature. I'd take it from Jenna herself, too, although technically "Pam" would have set her email name herself in that second example :-P
