On Wednesday's "Late Show," Gaffigan revealed to David Letterman that he thinks fish is completely disgusting, adding, "The best compliment you can give fish is to say it's not fishy." Then, he went off on other seafood, saying that lobsters are just "giant insects" and clams and oysters are "snots in a rock."
For a comedian who seems to have hours of material on Hot Pockets, it can be a little surprising to learn that he thinks any food is gross, but it's also pretty hilarious, too.
"The Late Show with David Letterman" airs weeknights at 11:35 p.m. ET on CBS.
