Quote from Robin in The Three Days Rule
Robin: So you might as well tell them you're on to them. Ted: Yeah. Or... I text them something that will really mess with their heads. Robin: Oh, I gotcha. Okay. How about... "I haven't told any of my friends yet, but I only have three months to live"? Ted: Not bad. How about "I once killed a man with a shovel, and those feelings are creeping up again"? Robin: Uh-huh. Uh-huh. I liked that thing someone said before about having three months to live. Ted: How about "I never told anyone this, but I slept with my best friend's mom"? Robin: Oh, that is good, but I feel like we keep coming back to that three months to live thing.
