I also learned that grown adults participating in """""""childish""""""" activities such as comic books/graphic novels, video games, and Rubik's cubes makes you childish, immature, undeveloped, and probably autistic. If you enjoy things not typically enjoyed by grown adults, you're probably a waste of life, and definitely autistic.
It's also worth noting that heteronormativity and homophobia are core tenants of 'good, honest comedy'. Reinforcing gender roles and sexuality stereotypes is especially hilarious, for example with assuming that a man who reads a gossip magazine is gay, and making a joke out of it. Because of this, it's worth noting that the episode is written by Graham Linehan (???). The gag could instead be making fun of the fragile masculinities and insecurities of the leading men in the show, but if that were the case, the homosexual stereotypes wouldn't be the punchlines, nor would the reinforcement of gender roles.
