Truly an art. And you didn't even touch the finer points of juxtaposition of praising and derogatory statements, using them in conjunction to coalesce a near-perfect crush, to first elevate their spirits then slam them into the ground with the force of a broken and ballistic theme park ride. For example:
"You, sirs and madams of the LRR crew, are the absolute pinnacle, the premier and pitch of the field of excrementory jokes, the kings of rubbish, the sultans of idiosyncratic festivities, and decadent exemplars of irrelevant and nonsensical behaviour. You are the exulted expeditors of death, robbing us of our merriment, and leading us to not just head in the direction of an early grave, but to run, leap, sprint, and vault with all the celeritous movement we possibly can propel ourselves to our own demise, merely to escape your terrible, oblique attempt at amusement and comedy."
Great sketch, guys, it made me happy in my ability to curse and swear with terms beyond expletives, biting to the very bone with each remark. Keep them coming!
