Set up a minority Out-Reach program as he is your leading 'minority' it is only right that he should run it.
Sit back and watch the ensuing carnage/car crash, smug in the knowledge that it was you that orchestrated it.
Whilst he is running headlong into the 'brick wall' that is being sacked and unemployable try and manoeuvre him into one or two inappropriate relationships with either other members of staff.
Ensure that
you have given him he has a vast array of highly inappropriate sexually explicit chat up lines for both male and femail colleagues as well as clients and that as Commander in Chief of said 'Out Reach' Program it is his duty to call a weekly meeting during which he must drop his kecks and show his team his putrid puss dripping willy whilst explaining that it is part of his new 'team building' initiative and that they too are expected to drop their kecks.
When both male and female staff have complied with the whole 'keck dropping' exercise make sure that he knows that for phase 2 of the team building exercise to take place he then needs to address the males in the team so that he can tell them that they should now brazenly and openly stare at the females genitalia and start 'thinking outside the box'.
As most of the males will only be able to think about being inside 'the box' the team building will have failed.....
Job done.
