Okay:

There is two area codes near where I used to live: 905 and 416 ("416 to the 905" -- Maestro). A while ago they didn't institute a "use the area code for everything" rule, so people who were from the 416 area code kept calling my dad's company (ie: his cell) thinking it was the 905 number. Now seriously, how dumb do you ahve to be? It's a different area code altogether, but same phone#. Sheesh.
