FARMINGTON — Teachers Lounge Mafia will present its third annual “Stale Milk and Sour Cookies” show, a combination of improv and all-original sketch comedy, on Friday and Saturday, Dec. 3-4, at the University of Maine at Farmington.

Proceeds from the mature-rated nights of irreverent laughter will benefit the Wobbly Feet Foundation and the A-T Children’s Project.

Beginning at 7:30 p.m., audience members will provide ideas that Teachers Lounge Mafia actors will play out in absurd and ridiculous skits.

Besides the sorts of games made popular on “Whose Line Is It, Anyway?” Teachers Lounge Mafia offers up its own, including the Facebook-inspired “Clickable.” The show also features obnoxious party guest The Drunk Confessor, the awkward romance of Shannon and Michael, and the premiere of the Middle Aged Mamas of hip-hop.

“Stale Milk & Sour Cookies III” marks the third anniversary of Teachers Lounge Mafia’s first performance. To help celebrate, the group has enlisted improv groups from around the state, including Portland Improv Experience, The Escapists and UMF’s Lawn Chair Pirates.

Proceeds will benefit the efforts of the Brochu family of Jay to raise money for the nonprofit Wobbly Feet Foundation and the A-T Children’s Project. Ataxia Telangiectasia (A-T) is a progressive, degenerative disease that attacks the cerebellum, which controls motor control coordination and affects a number of body systems. Both Brochu children, Brooke and Joshua, have been diagnosed with this rare condition.

Making up Teachers Lounge Mafia are comic actors Jeff Bailey, Natalie Bean, Alex Kreitzman, Gavin Pickering, Emily Pottle, Dan Ryder and Kyla Wheeler, several of whom have appeared on-stage as members of Lawn Chair Pirates and Curtain Raisers.

“Stale Milk & Sour Cookies III” will begin at 7:30 p.m. at Lincoln Auditorium in the Roberts Learning Center. Donations, suggested $5, will be collected at the door. For more information, call 578-0357 or visit [email protected].
