What the Feck?

Speaking of beligerant Irish people, Richard was painting the set for The Cripple of Inishmaan all day today and got to see a partial run-through. He said it's very good, but all "feck you" and "feck this" and "feck that". He wants to take Demi to it, but I dunno... She knows the Golden Rule ("Hear it, don't say it."), but it's awfully tempting for an 11-year-old to pick up cool swear words like "feck". "I'm not eating this fecking meatloaf, it's not me fecking bedtime yet," etc. I mean, Richard's 50 and he's been saying it all day.
