"Not a Father's Day" is a great How I Met Your Mother episode. I love the beginning of this episode where Barney explains The Cheerleader Effect, where a group of people look hot, but as individuals, each one has a flaw. I love how a girl calls thinking she's pregnant with Barney's baby. I love how Barney is excited once he finds out that she's not pregnant. The only thing I didn't care for was "Not a Father's Day". It was just stupid and not funny. I love the Lily and Marshall plot of wanting to have a baby. I love how Lily gets so drunk that she acts like a baby and Marshall has to take care of her.
