I fuckin doubt it. You said you dated the principal? I’ve seen him date my mom’s cat.
I fuckin doubt it. You told me you could run a mile in 10 seconds. I ran that in 10 minutes and I’m still out of breath.
I fuckin doubt it. You said you got a perfect score on the test? I got a 62 and I still remember the questions.
