I fuckin doubt it. You said you got into Harvard? I’ve seen you fail the entrance exam for the local pizza shop.
I fuckin doubt it. You told me you could solve the world’s problems in 10 minutes? I’ve seen you argue with your little brother for 10 minutes and still didn’t win.
I fuckin doubt it. You said you could beat up the school bully? I’ve seen him beat up my dad.
