Tenacious D have partnered with Queens of the Stone Age frontman Josh Homme’s charity the Sweet Stuff Foundation to raise money for victims of the Nov. 13 attacks in Paris.

The auction, which is underway right now, boasts a hodgepodge of Jack Black and Kyle Glass’ bizarre merch, tour gear and costumes. Stage props from the comedy troupe’s Rize of the Fenix tour, the duo’s Pick of Destiny fur cloaks and a handful of concert posters are just a few of the 13 items you can bid on right here. The auction will close on Jan. 5.

“Our friend Josh Home asked if Tenacious D would participate in the awareness and fund raising campaign in the wake of the recent attacks,” Black and Glass told Billboard. “We were eager to join the cause. This is our small but heartfelt contribution.”

Proceeds from the Tenacious D auction will go to Homme’s the Sweet Stuff Foundation. Homme founded the non-profit to support career musicians battling disabilities and illness, but it’s currently redirecting all donations received before the end of the year to Paris victims’ families. Homme and his Eagles of Death Metal bandmate Jesse Hughes also launched the “Play It Forward” charity campaign, which encourages other artists to cover their song “I Love You All the Time” and donate their earnings to those affected by the Paris attacks.

Eagles of Death Metal were playing a concert at Le Bataclan in Paris when terrorists opened fire in the theater, killing 89 people in attendance.
