So it's a horrifically hot day, and this guy's air conditioner is broken. So he goes to the store to purchase a fresh one, and there was a long, long line. He finally gets up to the counter, and asks for a replacement air conditioner, but at this point they are out of the kind he wants.
He goes to another air conditioner shop, a few blocks away. He goes inside, and there's a long, long line. He finally gets up to the front, gets his air conditioner and goes home.
He's sitting at home, and thinking how nice it would be to have some ice cream to go with his new air conditioner. So he walks to the ice cream parlor, and there's a long, long line. He finally gets his ice cream and starts walking home.
On his way home, he sees a limo drive by, and remembers that his brother's wedding is today! He rushes to the tuxedo shop, and there's a long, long line. He finally gets his tuxedo, and rushes over to the church. To get in, there's a long, long line.
The service is held, and he wants to give his congratulations to his brother and his bride. To do this, there's a long, long line.
During the reception, he wants to dance with his brother's new wife, to welcome her into the family. To do this, there's a long, long line.
They dance, and she asks if he'll get her some punch to drink. So he goes over to the refreshments table, and there's no punch line.
