That gnarly smell at Bristol Motor Speedway on Sunday wasn’t burned rubber, spilled beer or questionable track food. And no, it wasn’t the lingering stench from a human leg caught on fire.

Nope, it was Darrell Wallace Jr.

The ever-entertaining NASCAR driver got stuck in his bus prior to the Monster Energy NASCAR Cup Series Food City 500. Unable to exit through the front door, Wallace eventually escaped through … wait for it … the toilet hatch.

Watch him explain the bizarre dilemma in the video below:

Call us crazy, but we sense a Drano NASCAR sponsorship coming down the pipe.

Sunday’s race at Bristol was suspended after 2013 laps due to rain. Kyle Larson will lead the field when the race resumes at 1 p.m. ET on Monday.

Let’s hope Wallace avoids toilet-related detours on his way to the track this time — for all our sakes.
