ctblu40,
Anytime you manage to piss off BOTH managers with the same call (or, oddly enough, neither), you've got to be pretty confident it was correct.
Not saying that I would have had the presence of mind at the time, but "That's Backswing Interference!" might have been preferable to "That's Interference!".
BTW, I really liked "Not unlike..." - you phrase things like that and it's going to take them a couple of seconds (at least) to figure out what you even said - which, in my experience, has a tendency to kind of defuse the situation somewhat.
Good call, Blu!
