Quote from Marshall in The Best Man
Future Ted: [v.o.] Now Lily and Marshall had just found out they were having a baby. Marshall: I can't wait to tell everyone. Lily: Baby, no, we can't tell anyone. Not until three months. I don't want to jinx it. Marshall: That's a bit superstitious, don't you think? Lily: Whenever we board a flight, you lick the plane. Marshall: Have we crashed even once?
