"Houston, we have a problem. A sexy problem".
How much fun is it to watch the confusion and fear on the faces of non-Simpsons fans when a dinner party or suchlike devolves into a Simpsons quote-a-thon?
I actually can't remember which episode it came from, it might have been the Hellfish but I don't think so, it might have just been one of Grandpa's meandering anecdotes that went nowhere. It might have been the one about wearing onions in your belt (as was the style of the time).
