A longform improv comedy team that performed in New York City from 1999 through 2006. They were formed as a team for UCBT's Harold Night. They are one of the most lauded improv teams in the history of New York improv.
Among their notable achievements were The Neutrino Video Project in which the team would create a film as the audience was watching it.
Neutrino built its reputation, and likely prevented themselves from being disbanded, by having the first extended winning streak in Cagematch. They won the second-ever champion in UCBT's Cagematch against the heavily-favored Swarm. Neutrino was the first team to effectively pack the house and also to use the allowed time-out to garner votes from the audience. Among their more notable time-outs:
- giving beer to the audience
- having two girls lick the opposite side of a lollipop which led to them making out.
- stripping down to their underwear
- all of the above at once
- creating a multi-episode videotaped parody of VH-1's television show Behind the Music (Behind the Improv).
Winning so many Cagematches against established and "approved" Harold teams may have created a lot of long-standing bad blood toward Neutrino. Some suspect that this emnity contributed to Neutrino being "graduated" out of the UCBT a few years later.
Mother once "hired" Neutrino to perform their time-out in a Cagematch against Respecto Montalban. The audience wrote in Neutrino as the winner, even though they weren't on the ballot. Some of the improvisers didn't take it well. Write-ins were banned from that time on. It also led to the first three-way Cagematch a few weeks later in order to resolve the prior dispute.
At a later Cagematch, Neutrino debuted The Neutrino Video Project. When the UCB Theatre at 22nd Street was shut down, The Neutrino Video Project was paired with Mother: The Soundtrack for several months. After a somewhat controversial "graduation" from Harold Night but not into any other performance slot at the UCBT, Neutrino performed the video project at The PIT and eventually went on to become the first and only improv group invited to the HBO Comedy and Arts Festival at Aspen for their Neutrino Video Project.
