Lily and Marshall debate whether to find out the sex of their unborn baby in the October 17 episode of How I Met Your Mother. The couple tries really hard not to find out the sex, but it looks like some people in the group might be cracking when the gang comes together to paint the nursery in a neutral color.
Meanwhile, Ted agrees to go on a date, but chooses not to research the girl beforehand on the internet. The group interferes when they learn of Ted's choice, which leads him to believe that they are all too into each others' business.
Kal Penn will also be making a guest appearance in the episode as Kevin, Robin's new boyfriend.
