Test Subject for Hire

Go To

Barney: You know Homer? I got a great way to make money. I'm a human guinea pig.
Homer: You mean, like medical testing?
Barney: Yeah, medical, military, chewing stuff.

When a character is short on cash, they might consider getting hired by a drug company or some other institute as a test subject, usually for various experimental drugs or a new device.

Depending on the setting, the character will either experience really annoying but otherwise mundane side-effects at the worst possible moments, which are often Played for Laughs. Or the character might gain superpowers or some other fantastical phenomena occurring. When Played for Drama however, the effects of the drug could be disastrous. And in a superhero story, it could make for a nice origin story.

Truth in Television, at least once animal trials are complete and the pharmaceutical companies are reasonably sure it won't kill people. Still, there are lots of rules and regulations when it comes to human testing, and companies usually want test subjects that match the products target audience, so not everybody can just volunteer. Of course, a Mad Scientist or Corrupt Corporate Executive may not care much about these rules. In that case, a Disposable Vagrant is likely to show up to be Kidnapped for Experimentation. It can also happen that the test subject was forced to participate in the trial by someone else so that person can claim the money.
