OG

Mike Ogulnick, the man with the bushiest eyebrows in all of Chicago radio, now the radio host for the Texas Rangers. The mackest of the mack daddies.

OG is the very definition of a smarmy douchebag.

Most annoying of all, though, is the inexplicable narcissism that defines OG's broadcasts.

MJH were ripping OG because Jurko laid out $200 to buy breakfast for the ESPN staff and OG, upon spying the sumptuous spread, whined that "there's no butter for my bagels".
