My son and his bright friend decided it would be funny to teach Boca to make a farting noise. He's been doing it for months now and I have been responding with, "excuse me" hoping he will repeat it after making the noise. For weeks all I have gotten is a, "phwoot - thank you" from Boca. Yesterday he made the sound and then immediately said, "scusethank you". What's a Grandma to do!
