"...or pornography starring your mother will be the second worst thing that happens to you today"

So I'm sitting at Cashline today on my break, with a co-worker who has a very dry sense of humour and a fondness for first-person shooters.  We're having subway and watching trailers for the "really old" Team Fortress 2 (which is less than five years old, mind you).  We're watching the "Meet the Spy" trailer, and my co-worker knows a good line is coming up and is chortling like an idiot.  And then I'm completely blindsided by one of the absolute best lines I've ever heard:

"...no, the would be your mother!"  (drops a bunch of pictures showing the bad guy having sex with the scout's mother) "Indeed.  And now he's here to F*** us!  So listen up, boy, or pornography starring your mother will be the second worst thing that happens to you today." 

I wish I could say I did the gentlemanly thing, and just kind of smirked and let it pass.  But, alas, it was not to be.  Instead, I roared with laughter, and made sure to quote it about a bazillion times throughout the day.  And, of course, it was all done in that faux french accent.
