I liked them too! Douglas was more of your "classic" nerd, like Bernard in the old Maniac Mansion game. Adam, yes, might remind you of "Comic Book Guy" from the Simpsons; although that "genre" of personality/physical type is often given a harsher name by women such as myself who constantly get stalked by them when we dare visit a comic book or video game shop.
Hopefully Adam bathes more regularly than those guys do. (Also if Adam likes Frankie I probably wouldn't be his type anyhow. Unless his type is "female" which is entirely possible.)
