Quote from Future Ted in How I Met Everyone Else
Future Ted: [v.o.] So, suffice it to say, Blahblah did not turn out to be your mother. As for the girl I made out with at the party, there wasn't a doubt in my mind, that was your Aunt Lily. But you know that magical story of how she and Uncle Marshall met, it was worth preserving, so I kept my mouth shut. Ted: I guess I made a mistake. Must have been Alexa.
