1. This commercial borrows the poem The Laughing Heart by Charles Bukowski, without credit.
2. The use of this poem by a corporation might be considered ironic because most commercials are extremely happy (Except those commercials about animals or children in Africa). Also, the poems mentions oneself as marvelous, and to take chances, but this is commercial is about selling jeans. The poem is about life, and the commercial is about jeans.
3. Yes, I do believe the poem represents the reputation of the author. When researching Mr. Bukowski, many sites mentioned how his poems emphasized the lives of ordinary people. It also mentions how he wrote about American lowlifes. Mr. Bukowski is an American poet that is to told to influence social, cultural, and econmical atmosphere of his home, Los Angeles.
4. I discovered the answers to #1 and #3 by clicking the link, which transferred me to youtube. I ended up reading the comments of the video, then a user(s) mentioned the name of the poem, along with the author. I, then, looked up Charles Bukowski and read a few sites on his life and inspirations.
