Trolls are lurking everywhere. They hide out in the darkest corners of the internet with bundles insults in tow, and they run rampant on the sunniest parts of Instagram defecating on people's happiness. Most people who spend a sizable are likely to encounter a few trolls here and there, and these encounters grow exponentially if you're famous.
The comedian Patton Oswalt is a veteran at dealing with internet trolls. Through time and experience he has learned the art of ignoring them when healthy, and also engaging bitter trolls when the time is right.
This week, after Trump posted a rhyming tweet fit for a fascist version of Dr. Seuss, Oswalt did what any profession comedian does: he chimed in with his own poem.
