All proceeds from the $1.99 download will go directly to the charity. In addition, comedycentral.com will stream the entire broadcast online on Monday, April 14. Users will have the opportunity to donate to the charity via the Web site.

The October 2006 "Night Of Too Many Stars: An Overbooked Benefit For Autism Education" raised more than $2.5 million.

"Night Of Too Many Stars" will benefit a variety of Autism education programs around the country. The funds raised will support educational facilities that have recently opened or are about to open their doors, along with those already well-established model schools that are now developing innovative programs to provide vocational and life skills for adults with autism. Proceeds will also support outreach programs that provide training and consultation to families of very young children in their homes. Additionally, a portion of the proceeds will benefit Autism Speaks, the nation's leading autism advocacy group.
