Ted walks in on Robin's date sitting on the couch in the buff. When she later admits she hooked up with him, all the gang try it. Lily angers Marshall when she tries to think of 50 reasons to have sex. Although not a match, Ted starts to forget Stella by dating a new girl and successfully uses the "Naked Man" technique on her.
