英语笑话:家庭幽默：我知道你会帮我

I knew I could count on you!

Smith goes to see his boss in the front office. "Boss," he says: "we're doing some heavy house-cleaning at home tomorrow, and my wife needs me to help with the attic and the garage."

"We're short-handed, Smith." the boss replies. "I can't give you the day off."

"Thanks, boss," says Smith, "I knew I could count on you!"
