I dont even consider Old School to be a Ferrell Movie. He wasn't the main character. It was a good movie. But Talladega Nights and Night at the Roxbury were better.
I will say that Farrell had some classic lines in Old School. His bits were more memorable than the other actors. Running naked, "you're my boy blue" and dust in the wind are the 3 most memorable parts of that entire movie.
I don't know man.
Your my boy blue is definitely memorable, but really to me just because it's nice and short. It's a one liner. But some of my favorite quotes are:
"True love is hard to find, sometimes you think you have true love and then you catch the early flight home from San Diego and a couple of nude people jump out of your bathroom blindfolded like a goddamn magic show ready to double team your girlfriend... "
"Max, can you earmuff for me? We are going to get so much ass here, it's going to be sick. I'm talking like crazy boy band ass. "
"Alright, let me be the first to say congratulations to then. You get one vagina for the rest of your life. Real smart Frank. Way to work it through. "
"At this point, you might be asking yourself, 'why am I holding this 30lb. Cinder block in my hands? You might also ask yourself, 'why does this cinder block have a long piece of string tied to it? And finally, why is the other end of this string tied securely to your penis?"
Among others, most that I can't post due to profanity or implied profanity. Most are not by Ferrell though.
