Quote from Future Ted in Pilot
Robin: Wow, that is one bad-ass blue French horn. Ted: Yeah. Robin: Mmm. Ted: Sort of looks like a Smurf penis. Future Ted: [v.o.] Son, a piece of advice. When you go on a first date you really don't wanna say "Smurf penis". Girls don't ordinarily like that. [Robin chortles] But that was no ordinary girl.
