sit down and have a beer
The offer made, via Twitter, in August of 2009, from Heather Armstrong to Jenny Lawson to settle the conflict of the mythical hobbit incident over alcohol at Dooce's expense. Note: technically, the offer was to "sit down and have a drink," but people have since referred to it as an offer of a beer, so that is usually how it is referenced. I do not know if Heather Armstrong and Jenny Lawson ever had a drink together, but I do know there was a formal apology made by Heather Armstrong for the mythical hobbit incident.
