...between Stephen Pastis (of Pearls Before Swine) and John Glynn (the boss of United Press Syndicate).
Some time back Pastis put up this hilarious video (Scott Adams even put it on his blog) of him visiting and annoying the daylights out of Glynn.
He does this to Glynn in today's strip. I don't know if Pastis just hates Glynn's guts (he must have rejected Pastis' work) or they're great friends and Pastis loves picking on Glynn. Either way, it makes for a bucket of laughs, thank you.
