Lisa: Which one's Ed, which one's Larry?
Ed and Larry (simultaneously): Doesn't matter.
Two characters, usually in a school setting, to be the mundane Greek Chorus. They may or may not be snarky and unlike the Greek Chorus, they don't break the fourth wall very often (if at all). They're completely ordinary... and no, we don't mean as in the Ordinary High-School Student, or the Badass Normal. They're ordinary. Often the best friends of the main character (who is an Ordinary High-School Student) before all the weirdness with aliens, robots, magic, demons, harems, etc.
Some pairs become involved in the plot less and less as the series progresses, especially if the plot becomes more serious. Given what usually happens to people involved in the plot, it's probably for the best. However, it's not uncommon for Those Two Guys to also become popular and even iconic characters in the series.
Their personalities usually sharply contrast, e.g. calm/hyper, jock/geek, etc., or their appearances contrast, e.g. short/tall, thin/fat... When they don't, they will be exactly the same. They might even wear Coordinated Clothes. Their names are often esoteric (either too complex or too simple to stand out), plus their non-involvement with the plot usually results in them being called "Those Two Guys". If part of a band of four, they will be paired with an Odd-Couple type, usually protagonist/narrator and a best-friend type. They will often split into two groups of two, usually with the two main characters having a profound (or at least more plot-relevant) conversation while the other two (usually the group dumb guy and the big guy/tough guy) do something contrastingly goofy, like roughhousing or mindless bullshitting (see Stand by Me or Good Will Hunting , to name just two examples).
Occasionally, we get a Lower-Deck Episode from their point of view. Expect to ask someone who they are after a few episodes.
Compare the Beta Couple, Heterosexual Life-Partners, Tomboy and Girly Girl, Sensitive Guy and Manly Man, Straight Man and Wise Guy, and The Dividual. This trope may sometimes overlap with Red Oni, Blue Oni trope (though that trope isn't always exclusive to the Those Two Guys trope). Despite the similar name, Those Two Bad Guys have very different personalities from Those Two Guys... even if they are bad guys. If there's only one of these guys in a romance-based series, he's likely a Bromantic Foil. Also associated to members of a musical group who are not the Face of the Band.
