To keep its 20-something fans satiated, TeenNick is about to sub in two more (old) shows to its popular The ’90s Are All That programming block.

Beginning Sept. 5, repeats of Hey Arnold! and Rocko’s Modern Life will replace Clarissa Explains It All and Doug Monday through Friday nights alongside faves like All That and Kenan and Kel. The two-hour block airs on weeknights from midnight to 2 a.m., and re-plays from 2-4 a.m. for the nation’s serious night owls.

TeenNick chose the two animated series after polling its rabid fans via social media sites. (And for the uncool over 30, Rocko is an Australian wallaby while Arnold is a fourth grader with a football-shaped head. See what you’ve been missing, Gen Xers?)

TeenNick has seen a double-digit boost in viewership since launching the late-night programming block on July 25. The reruns are a throw back to Nick’s roots in 1991, when it first expanded into original programming with Ren & Stimpy, Doug and Rugrats.
