I do not watch TV anymore (occasional games on the switch or ps3 with my wife or a movie on my laptop plugged into the tv screen... but no actual shows), and the Simpsons had long gone downhill when last I watched. However, my wife and I regularly chuckle at lines we remember and I thought I'd share a few...
"This is the most egregious case of false advertising since my suit against the film 'The Never Ending Story'"
Homer has invitations made for his BBBQ party. When questioned about the extra 'B' he replies that it stands for BYOBB. When questioned about that extra 'B' he replies "typo".
In response to finding a seemingly dead grammar robot:
Homer: "Linguo! Dead?"
Linguo: "Linguo IS dead."
Not sure why I thought of these three or why I felt the need to type them up.
