Tv.com's description of the episode reads:
Robin attends Lily's bridal shower and finds the gift that she brought is out of place.
That "gift" happens to be a black... well, in the spirit of PG-13, fake male part. She even gets an old sweet lady to "give" the gift to the bride. Sound at all familiar?
If, in next week's episode, Ted fall's in love with a cute Chilean girl that he met in an engineering class, I might have to consider legal action.
