Squirtgun sprouted from the fertile farm land of Indiana in the Fall of 1993. They began recording almost immediately, and signed with Lookout! Records soon after. Squirtgun's first release, the CD–EP Shenanigans, hit the streets in the Spring of 1995, with their debut self–titled full–length appearing that Fall. This full–length CD contained the song "Social", which was featured later that same year in the opening credits of the Kevin Smith movie Mallrats, and the song "Make It Up" featuring guest vocals by Green Day's Mike Dirnt.

1996 brought Squirtgun's second CD–EP, Mary Ann, a tribute to their favorite castaway from Gilligan's Island. A video was filmed for the title track, and featured an appearance from Mary Ann herself, actress Dawn Wells. The video was released in the Spring of 1997 and shown on MTV's 120 Minutes and put into regular rotation on MTV2.

Squirtgun's second full–length, Another Sunny Afternoon, was also released in the Spring of '97. Several songs from Another Sunny Afternoon were featured in major motion pictures and TV shows, including "Come On Let's Go" in The Extreme Adventures of Super Dave, and "You're the Greatest" on Fox Television Network's Clueless sitcom. In the Fall of 1998, after 5 years of high activity and playing shows with the likes of the Bouncing Souls, the Queers, Blink–182, Less Than Jake, At the Drive In, Anti–Flag, and NOFX, Squirtgun went on a hiatus in order to pursue other interests and other band projects.

Mass and Dan joined Screeching Weasel, recording and releasing several albums, including Television City Dream, on Fat Wreck Chords. The bass–drum duo also formed Common Rider with singer/guitarist Jesse Michaels (formerly of Operation Ivy), releasing two full–length albums, and touring extensively in 2002. Dan also provided his amazing drum skills to albums by the Mopes, the Methadones, and Even In Blackouts, to name just a few. Mass also continued his producing career, primarily in Sonic Iguana Studios, which he founded in 1990. In this studio, many notable punk bands created legendary punk albums, including Anti–Flag, the Queers, Born Against, Screeching Weasel, Rise Against, Teen Idols, Groovie Ghoulies, Eyeliners, Riverdales, the Lillingtons, Moral Crux, Big In Japan, the Smoking Popes, and many more.

Matt got his MFA in creative writing and began teaching in the Academic Studies Department at the Art Academy of Cincinnati, a four year college of Art and Design. His poems and reviews have been published in numerous literary journals, including Conduit, Ploughshares, and Spinning Jenny. He is the editor of Forklift, Ohio: A Journal of Poetry, Cooking & Light Industrial Safety. Somehow he also found time to play and record with the bands Clifford Nevernew and Travel.

Flav, meanwhile, also hit the books, earning a PhD degree in molecular genetics and publishing manuscripts in several respected scientific journals, including Development and Molecular and Cellular Biology. He also founded guitarpunk.com and the GPC guitar company, designing original guitars used by bands such as Alkaline Trio, Screeching Weasel, the Queers, Allister and many more. In his spare time, he fronted his punk'n'roll band, the Simians.

In the summer of 2001 Squirtgun regrouped and began work on their latest release, Fade To Bright, for Honest Don's Records. This CD represents the band's finest and most diverse set of songs, and oodles of guest appearances. Fade To Bright was released in the Summer 2003, supported by a US tour. In the Fall of 2003, legendary punk rock drummer Mike Felumlee (Smoking Popes, Alkaline Trio) replaced Dan on drums, and Squirtgun hit the road with the Ataris, Hopesfall, and Planes Mistaken For Stars. In the spring of 2004, Squirtgun toured the U.K.
