I don't mind them plugging Big Mouth because they talk a lot of crap on Big Mouth, just like they talk a lot of crap on GNW.
Having Mark on GNW is pretty... yeah. I think it would have seemed less tacky and gimmicky if they'd had Jason on as himself to drop some subtle (or not so subtle) plugs. It's commercial TV and they've got to do the plug thing, I know, but in character? Hmm.
The massive glut of "Deception" fragrance ads is growing increasingly annoying, too. I'm still prepared to give it a chance since it's between two shows I watch anyway... But damn, it's being pushed really hard.
