For me, it's a three-way tie between Jak II, Sonic Adventure 2, and PS1 Spider-Man.
In China they say, chiki chang wang Charlie Chan chika chaka chuka chon.Popular opinion faggot here, but MGS1.
He is unbearable during EVERY. SINGLE. CODEC call. It's both hilarious and aggravating at the same time how little attention he pays to anything in the MGS series, because every control and bullshit plot twist is literally spoonfed to you to make the game as cinematic as possible and he just shits on that idea completely. He's literally the dude that talks through the fucking entire movie.
