Classics that won't leave you Depressed

I remember from my high school days that most of the literary classics they made us read were really depressing. Here's a few classics that are happy / not totally depressing. (No guarantees anything is spelled correctly)

• A Merchant of Venice, Shakespeare
• A Mid Summer's Night Dream, Shakespeare
• The Taming of the Shrew, Shakespeare
• (Basically any comedy by Shakespeare)
  
• My Antonia, Willa Cather
• O Pioneers, Willa Cather
• Brothers Karamazov, Dostoyesky
• The Inferno, Dante
• Cantebury Tales, Chaucer
• Silas Marner, George Elliot
  

As you can see, the list is short. If you have any to recommend, let me know.
