BTW I do say "arrrrgh" a lot -- picked it up from my daughter a few years ago. My husband teases me about it sometimes and says, "Are you practicing being a pirate?"
Me, too! Not excessively, as was a guy on crack at the ER (daughter was being treated for back problems from playing basketball). The guy was barking like a dog. My daughter said she overheard him saying that he *was* a dog!
