1. The commercial borrow's a poem called The Laughing Heart written by Charles Bukowski.
2. The use of this poem by a corporation is ironic because the purpose of the commercial is to convince you to do a certain thing, while the meaning of the poem is to have an open mind and free will.
3. I don't think the poem reflects the reputation of the author. After a good amount of research on Charles Bukowski, all I can tell is that he was a depressed drunk who wrote about alcohol, sex, and how much he hates his job. This poem, on the other hand, feels much more upbeat. I was surprised when researching Bukowski to find out how dark the majority of his works are.
4. For #1, I searched the first few words of the poem using Google. For #3, I used Google to search "Charles Bukowski." I read from Wikipedia and a site I found called Goodreads.
