Family Guy tries too hard to come off as an inside-joke to pop/80s and obscure references.
"ha ha, look at us, we are so witty with our obscure 80s pop reference, lets toss 50 of them into one episode"
Dont get me wrong, I still watch the show and find it funny (but it has gone downhill the last while), but to think its some sort of 'big cosmic inside joke' while tripping just seems a bit silly.
If I'm going to be watching something on TV while tripping, its going to be something far more interesting and deep than family guy.
You know, thats one 'thing' with psychedelics - they seem to make you think that EVERYTHING is steeped with inner deep cosmic meaning. I recall getting a bit annoyed one trip because I couldnt even blink without that blink seeming to cause some 'great mystic insight' - some times blinking your eyes is simply blinking your eyes, and you know? family guy is just pop-trash comedy TV that is good for a few laughs.
On a somewhat related note, I recall being on 4 hits of LSD with some friends. I decided to go outside for a few hour walk, when I got back in, they were watching South Park, with the Paris Hilton vs Mr Slave slut-off contest. I got in just as Mr. Slave was fitting paris hilton up his ass, you know, the last thing i want to see when frying on 4 his is Mr. Slave fitting paris hilton up his ass, I simply left the room, for some reason they thought it was the funniest shit ever, and actually got a bit pissed off at me for going to the bedroom to be alone.
