One of the best HIMYM Episodes, "The Naked Man" was rated superb in an official episode guide! It was impresingly hilarious and the picture above is a memorabilia that Lily (Alyson Hannigan's character), together with the other 4 characters, stuggled to fill due to a Marshall's only-love-for-sex challenge.
This one's two thumbs up. :D
