Eeyore sez, "I am currently unemployed, so I spent my day today LOLing the entire 'Rocky Horror Picture Show'. Some of them are only funny if you've seen every LOLcat on the net, some are only funny if you know the RHPS script by heart, some are only funny if you know all the RHPS call-backs by heart, and some of them aren't very funny at all but that's life."
Speaking as someone who spent a million consecutive Fridays out of my face watching this movie and shouting blearily at the screen, I can vouch for this.
