Lest you think the NFL is a humorless corporate monolith, remember that April 20 is the date the league opens its annual drug-testing window. Yep, beginning on the unofficial weed-smoking holiday, players can be drug-tested. High comedy, indeed.

Unless you're Steelers running back Le'Veon Bell, who was suspended for the first two games of the 2015 season following an arrest for DUI and marijuana possession.

Bell is one of the most dynamic backs in the league and an important cog in an already-explosive Steelers' offense. The hope is that he can stay on the field in 2016 (in addition to the two-game suspension, he missed the final eight games of the 2015 season with a knee injury) since otherworldly talent Martavis Bryant has already been suspended for all of 2016 after violating the league's substance-abuse policy.

And in case you're wondering, NFL commissioner Roger Goodell practices what he preaches -- at least in this instance.

"I am randomly [drug-]tested," he said back in 2014, "and I am happy to say that I am clean."
