Much like everything else on television, friendship is not what it seems.
During a musical appearance on The Late Show, the fellow comedians got cozy in front of a forest-inspired backdrop to sing a song about friendship. However, when it came time to dedicate the song to their individual best friends, they just were not on the same page. While Colbert wholeheartedly declared his guest his very best friend, Martin was not so quick to return the favor.
"I'm sorry, Stephen. We're just not friends," Martin declared after strumming away on his banjo. "We've met like twice." Awkward!
The Father of the Bride star didn't exactly let Colbert down easily, either.
"TV friends isn't the same as being real friends," he explained. "I think of you as an acquaintance."
