Last Man on Earth star Will Forte stopped by The Tonight Show Starring Jimmy Fallon Thursday night, where he had his disgustingly adorable beard tested for various bacteria. Will was concerned about several reports of fecal matter being discovered in the beards of several friends and colleagues. So a doctor from the Microbiology Immunology Molecular Genetics Parasitology Division of UCLA swabbed and tested Will’s beard.
To ease Will’s anxiety over the pending results, his friends Jon Hamm and Rachel Dratch sat beside him as he learned that his beard tested positive for pseudomonas, Serratia marcescens, staphylococcus, and yeast. (By the way, these positive results came despite him showering right before the test.) Luckily for Will and the people he hugs, his greatest fear — having poop in his beard — was eased when that test came back negative.
The Tonight Show Starring Jimmy Fallon airs weeknights at 11:35 p.m. on NBC.
