A prank? It was a rather bad prank. Not in just in the political correct sense but in the "comedy" sense. It's awkward and weird; it's not funny.
Had they hired a bunch of Chippendale's dancers to serve booze (because alcohol does wonders for your productivity) and big hairy bikers to give massages (as opposed to the girls in tight t-shirts they no doubt retained for the event,) would be a prank.
