He's probably right.
And why is "prostitute" always considered the first job? Makes the big assumption that consent was invented before jobs. If consent was not invented before jobs, then "pimp" is probably technically more likely than that anyway...
Ah you should have put pimp in the poll though. Even if you grant prostitute as the potential answer, one must grant that pimp is more likely, strictly speaking, nay? Just trying to think like Urg and Grg here.
