From July/0/4, 2005 to July/0/2, 2006, Kyle Mcdonald, a Canadian boy, finally realized his dream of changing villas by bartering with a red paper clip. He signed a book publishing agreement with Random House and sold the filming rights to Hollywood DreamWorks. The main process of his successful communication is as follows:

A red paper clip → a fishtail ballpoint pen → a skull handle ornament → a camping microwave oven → an old household generator → a memorable beer barrel+a bill (to be filled with beer) → a snowmobile → a free holiday arrangement → an old dual-purpose van → a recording studio contract (50 hours of recording and 50 hours of mixing production) → a free rental in Phoenix, USA.
