There’s one aspect of the holiday season that’s got Stephen Colbert seriously bugged. On Friday’s broadcast of the “Late Show,” the comedian poured scorn on the Christmas custom of kissing underneath the mistletoe. “This one is a messed up tradition,” Colbert said. “If you catch somebody underneath mistletoe, tradition says you can kiss in that human being whether they want it or not.” “It should be called mistle-Trump,” he added, in reference to President-elect Donald Trump’s pre-election comments about being able to grab women’s genitals. “Donald Trump asserted if you’re a star, you can grab them by the holly and they can not stop you,” Colbert quipped.The comedian after asserted people shouldn’t call him a party-pooper due to his disdain for the practice 'cause “the real pooper here is mistletoe,” as the word in fact derives from “mistle” meaning “dung” and “tan” meaning “twig.” “Oooh, kiss me! I’m standing under the shit-stick! So romantic,” Colbert joked, before explaining how the plant spreads (via birds pooping the seeds out) and asking why, given its poisonous nature, people did not just “hang up a bag of cyanide capsules to kiss underneath?” Check out the full monologue above.
