Family Guy Wiki

Does anyone know which episode an elderly woman shouts down from the bedroom to her husband and says something like 'We just got a mention on the Family Guy'?  I think it was a recent (ish) episode.  It's a nod to Howard's mother from the The Big Bang Theory.  I think the man then shouts back someting like 'Is that the one with the alien?'  She replies with the line 'No, that's the American Boy!'
