Next to being in Brazil, the best way to experience the fantastic thrill of watching the world's best footballers play at the 2014 FIFA World Cup will be to see the action live on TV.

There's just one big problem for football fans in football-crazy China. The 11 hour time difference between Rio de Janeiro and Beijing means that games can only be seen live in China from the ungodly hours of 3:00 a.m. to 6:00 a.m. starting June 12.

If you're a Chinese salaryman, staying up that late leaves you with just two choices: don't go to work that morning or buy one of those increasingly popular fake doctor's notes that certify you were sick, so that's why you didn't go to work today.

These fake doctor's notes or sick leave slips are freely available on Chinese e-commerce sites such as Taobao, China's most popular e-commerce site and the Chinese equivalent of Amazon and e-Bay.

A really authentic looking doctor's certificate with a hospital's stamp and a barely readable note from the doctor can now cost as much as $50 or RMB300.

Before the World Cup, these fake doctor's notes sold for as little as $0.16 or RMB1.00.

Prices currently range from $2 to $50. The final price depends on the duration of the claimed sick leave and terms of the medical certificates.

One vendor is selling a sick note for chronic appendicitis valid for three days starting from the World Cup opening on June 12. The sick note comes with the seal of Peking University People's Hospital.

Chinese media reported some football fans are stocking up on these doctor's notes o to watch the World Cup live.

Selling doctor's notes as doctor's notes is illegal but vendors circumvent that with a literary sleight-of-hand by describing their notes as "proofs of diagnosis."

One online vendor said he sold 10 doctor's notes in one day and about 100 since he began last month. Acute lumbar sprain, acute appendicitis and nervous headache and are the top sicknesses requested on the fake doctors' notes.
