Posts on Twitter wished visitors a "Happy 90210 Day" as die-hard fans of the "Beverly Hills 90210" teen drama showed their love of the Fox show that featured stars such as two-time Oscar-winner Hilary Swank, Shannen Doherty, Jason Priestley and Tori Spelling, Chicago's WGN-TV reported.
Fans of the original "90210" marked the event with parties and tributes to the Beverly Hills clique by dressing up as their favorite teen cast members, reports said. Some faithful fans were also forming "watch parties" to view their favorite episodes from the 1990-2000 series (not to be confused with the 2008 "90210" series on the CW ).
"Today, in celebration of 90210 day, let's take a moment to remember that dude who played Dylan, whose name I can't even recall," one Twitter poster wrote of Luke Perry's character.
"Today is 90210," another Twitter post read. "Get your drama on."
Some Twitter posters apparently weren't caught up in the celebratory fervor.
"According to the calendar, today is 09.02.10, or 90210," one said. "You are now less intelligent for knowing this. Cheers."
