The “30 Rock” star most recently offended Greyhound Bus Lines while issuing a half-apology for his unruly behavior aboard an American Airlines flight earlier this week.

“There are many now who walk the aisles of an airplane with a whistle around their neck and a clipboard in their hands and they have made flying a Greyhound bus experience,” the actor wrote in a Huffington Post blog of the strict airline personnel who booted him off the plane Tuesday.

A representative for the bus company immediately issued a statement in defense of its services, expressing confusion as to why the ground-travel bigwig had been dragged into the showdown.

“I don’t know why he’s mentioning Greyhound, but we take pride in our safe and enjoyable service,” the rep wrote in a statement.
