Mo Farah won the New Orleans half-marathon in a record time of 1 hour 59 seconds, but his winning moment was slightly eclipsed by the interview he participated in afterwards. News anchor LaTonya Norton was perhaps having a bad day when she asked the Olympic gold medal winner: "Haven't you run before? This isn't your first time?" To his credit, Farah answered her question gracefully, but the moment has gone viral.

Have you ever made a gaffe on a similar scale? Tell us the most embarrassing question you've ever asked somebody, and how you recovered from it.

• In our haste to put up this open thread, we made our own embarrassing gaffe: it was a half-marathon, not a marathon. A marathon in 1 hour 59 seconds would be beyond even Mo Farah. This was corrected at 16:40 on 26 February 2013.
