Created by the 33-year-old "Neighbors" star and Lauren Miller Rogen, Hilarity for Charity is a movement to raise awareness of Alzheimer's disease among millenials, reported The Wrap.
With a donation of USD 10 to the organization, fans can get to enter a contest to attend Franco's 'bar mitzvah' as Rogen's VIP guest on October 17. Other prizes include t-shirts and dinner with Rogen.
The contest will run through October 10 in partnership with Omaze, a crowdsourcing-based fundraising platform.
Previously, Rogen offered himself as a date to a prom-themed variety show featuring Joseph Gordon-Levitt, Sarah Silverman, Craig Robinson among others.
