Rush roll
When a comment on a blog references a supposed Rush Limbaugh comment or video, with hotlink, that - rather than lead to a Rush clip - instead leads to a video of the auto-fellating walrus (on Youtube or the Sadly No! site's post "Sometimes a Walrus is Just a Walrus" that first introduced the pseudo-controversy over Chris Matthews referring to Rush as an "underwater Walrus").
I thought I was going to see Limbaugh delivering a profound insight, but the link turned out to be nothing but a Rush roll...
