Hi

Can someone help me find this song I saw a while ago, I only remember the video.
The video consists of a Chinesse man only in his underwear dancing around in his apartment and exercising on a stationary bicycle, doing all he can to get sweaty, and he is pretty sweaty. And at the end of the video he takes his sweaty underwear and puts it in a box and mails it to someone who then receives the underwear believing it was sent from some female and starts sniffing it.
Any help appreciated
