Clowns Pence Over Debate Housefly

LeBron James laughed his ass off over the housefly that parked itself on Mike Pence's head Wednesday ... saying straight-up he believes it went down 'cause the vice president is "\ud83d\udca9"

Bron was locked in on the Kamala Harris-Pence debate while his Lakers enjoyed an off day from the NBA Finals ... and when the L.A. superstar saw the bug land in the VP's hair, he didn't hold back.

"Ya'll know what flies favorite destination is right??!!" LBJ said. "Yup you guessed it."

LeBron added a bunch of crying face and poop emojis ... before finishing it all off with "FOH" -- an abbreviation "f*** outta here."

Of course, Bron has never been shy about his disdain from the current White House…
