British Jokes

I listened to the raid and heard that "Johnny Depp had never appeared in Manchester. It was a joke."
Now I take an Academic writing class. My teacher is a retired gentleman and he said, "I'm 96 years old." None of my classmates laugh nor surprise. My friend says "it's his joke." What's the point of these jokes if no one laugh at about it?

YUZU (Japanese restaurant)

I had a "Tendon" lunch at a Japanese restaurant "YUZU". The restaurant opened in August 2010. It's a new restaurant and a web site isn't ready yet but taste is very nice! This Tendon lunch costs only 5.95 pounds. I'm happy to find good quality and reasonable price Japanese restaurant in Manchester.
