Quote from Barney in Platonish
Barney: Please, Ted and Robin are not platonic. Just like me and Robin are not platonic. Just like no two single people in the world are ever platonic. Symposium. Two people are only platonic if in the next 20 minutes, there is no chance of them hooking up. Truth is, I only know of one genuinely platonic relationship.
Lily: You and me.
Barney: Don't make me laugh, Lily. You want to hit this so hard. Seriously, she's playing footsies with me as l... Ow! No, I'm talking about Marshall and Robin. [v.o.] Marshall and Robin wouldn't hook up even if this happened.
[fantasy, Lily runs into MacLaren's with a bomb strapped to her chest as Marshall and Robin talk:]
Lily: Marshall! Robin! If you guys don't full-on make out in the next 20 minutes, they're gonna blow me up and everyone in this bar!
Marshall: Oh, God, no. Anyone but Robin.
Robin: I really don't want to do this.
Lily: Guys, we have no time. Just do it!
[19 minutes later:]
Marshall: I'm sorry, baby. I just... I can't do it.
Barney: And the only survivor was me, because I was upstairs banging Ted's mom. What? Get that blond girl's phone number? Challenge accepted.
