Wa-hoooo! Porno!!! Cool! I'll take 2... with a side of softcore to pack out the corners...

Near as I can figure, a good number of the people ghosting porn sites at work are often afraid of being "IDed" surfing from home... (A load of bollox really)

TO answer #1, well, maybe for you it gets borning, but for some, it 'flips the switch' every time

and to answer #2, well, there are a LOT of people in the adult entertainment industry, and odds are good their mothers already know...

#4... well, what's the big deal... look 'em straight in the eye and say "HA HA!!! You got fired/demoted for surfing porn sites at work, you stupid, stupid idiot!"
