Quote from Marshall in Slapsgiving 3: Slappointment in Slapmara
Lily: Like I was saying, you need to harvest the anger of others into your own slap. Now dig deep. Can you think of anyone, anyone at all, who hates Barney Stinson? [laughs] I know, I almost couldn't get through it with a straight face. Marshall: There are just so many people who hate Barney's guts.
