One of the foundational truths of Comedy TV is that Danny DeVito is not afraid of getting weird and gross for the sake of Frank Reynolds earning laughs on It's Always Sunny in Philadelphia. And we absolutely love him for it. His character's latest evidence of stomach-churning debauchery occurs during the FXX comedy's first big Season 18 trailer, as seen above, and if the implications are correct (not those, Dennis), Frank is totally making out with a dead body.
