You know, I didn't see anyone bring this up with regards to Chris getting rejected as a sperm donor, but it's probably worth mentioning that sperm banks are highly selective. It's a business, not a democracy, and the women who pay to get their eggs fertilized tend to want the best their money can buy. Hence, not only do they screen pretty heavily for health issues (relatively common things like diabetes will get you rejected by most sperm banks) but also on the basis of attractiveness (they tend to reject anyone who is too short, overweight; even certain ethnicities if you can believe that) and education (college degrees, especially from Ivy Leagues and the like). So yeah, an unemployed obese manchild like Chris who barely got his CADD degree isn't likely to qualify. Not to mention that they'd want full medical and family histories, which quite frankly I don't think Chris would be competent enough to provide them with.
So yeah, another failure in Chris' life, but its not exactly surprising given that a significant majority of us would likely be passed up by most sperm banks. The key difference is that most of us aren't desperate or hopeless enough to try making money by donating sperm. I mean, most of us could at least get a job flipping burgers or something before that.
