Kelly, Harder - revisited

me: her last name is Harder?
Co-worker: yes

me: so the phrase "Kelly, harder" also passes as her whole name?
Co-worker: I guess so..

me: I bet when she's having sex and her boyfriend shouts"kelly, harder" repeatedly, she gets freaked out
Co-worker: why would she get freaked out?

me: Uh, because it probably feels like she's fucking a bill collector. Hell-o.
Co-worker: You might be right. I'll ask.
