Trudy (Danica McKellar) & Rachel (Busy Phillips)
Did he or didn't he? Thomas won't spill whether or not Ted had a threesome with Trudy and Rachel, but he does confirm that Trudy, who also appeared in the "Pineapple Incident" episode, is not the mother.

"Ted had two of his craziest drunken nights around that girl," Thomas says with a laugh. "It would be just sort of a weird way to meet the mother of your children, and also he would have already met her. … It's funny that two of Ted's just craziest drunken nights involve Winnie Cooper from 'The Wonder Years.' … 'How I Met Your Mother' is to some extent a story about all the insane nights of sowing your wild oats and whatnot."
