I get what you're saying, but the eating and the spiciness of the wings actually contribute to the quality of the interview.
Eating a meal with someone is disarming and contributes to the relaxed, ungaurded nature or his guests.
Consuming spicy food, particularly extremely spicy food or spicy food in great quantity releases endorphins which.
So while yes the eating/reacting to how hot the sauce is does interrupt the flow of the interview somewhat, it does help him get good/candid answers for his guests.
So while his research team is outstanding and he's a talented interviewer in his own right. The hot wings do serve a role in the interview as more than a clickbaity gimmick.
The DJ Khaled one was him just completely embarassing himself unintentionally. Funny because he's so full of himself. Conan's was funny, but you knew it was going to be before watching because it's Conan
