Nude Peter

Me:
Family guy is basically what keeps me watching Comedy Central, it is the balance between fat Americans and really pretty wives (I am not lesbian or bi but you have to admit Louis is pretty). It's ironic and makes no utter sense but that is what makes it amazing. If Peter wasn't Catholic I woudld think he was the stupidest awesomest person in the world. Also I just love Stewie he is a freaking genius.

My mum:
What the freaking hell is this you are watching? It is utter crap and the amount of times I have heard the word penis from in the lounge..... wait are you typing this???????

Peter goes back to the year 1984 once again and reinvents his entire past, present, future, and indentity into a smarter, darker vengeful murderous anti-hero of justice plotting his revenge towards the Family Guy writers for nearly blinding his edge in the 17th season long arc full of self reconstruction, hatred, redemption, honesty, mass homicide, realistic background storytelling, and awesome character development. Karen, Mickey, Francis, and Thelma will be an epic family team who are seeking retribution for the writers actions in this action-packed psychological sociological adventure to redeem the show's name. It will one hell of an explosive season in 3D anime.

I’m trying to find an episode that lives rent free in my head but the details are blurry.

Brian is talking to Stewie I believe but I could be wrong. Someone is taking a story about panties being shoved in a mouth and the funny part is Brian’s tail goes from a slow wag to fast as he gets more excited. I think Brian says “gross” with a smirk.

I’ve tried to search in scripts but I think I’m missing a key detail. I had hoped someone might remember the scene better than me and could point to the episode.

Thank you!!
