The Fat EP is an EP by the American punk rock band the Descendents, released in 1981 through New Alliance Records. It was the band's first recording with singer Milo Aukerman and established their presence in the southern California hardcore punk movement, with short, aggressive songs that represented a shift in style from their previous new wave and surf sound. The EP was re-released in later years as part of several compilation albums.

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.
