Two Things at Once is a compilation album by the American punk rock band the Descendents, released in 1988 through SST Records. It combines the band's 1982 debut album Milo Goes to College with the 1985 release Bonus Fat, itself a compilation of 1981's Fat EP, 1979's "Ride the Wild" / "It's a Hectic World" single, and the track "Global Probing" from a 1981 compilation titled Chunks. Two Things at Once has been described by critics as an essential collection of the band's early years.

Frank Navetta was an American musician who was the original guitarist of the punk rock band the Descendents, which he co-founded. He formed the band in Manhattan Beach, California with Dave Nolte in the late 1970s and played on their 1979 debut single, the Fat EP (1981), and their first album, Milo Goes to College (1982). Navetta then quit the band and moved to Oregon to become a fisherman. He collaborated with the Descendents again on the 1996 album Everything Sucks, and prior to his death in 2008 had been working on new material with original Descendents members Bill Stevenson and Tony Lombardo. In 2021, the band released this material on the album 9th & Walnut, which has been critically lauded for Frank's songwriting and playing.
