Since Conan asked in an early episode (I think the David Sedaris one) about free advice regarding his memory "problems," maybe he can have a two part thing where he has Seth Rogen (because of his Hilarity for Charity) on one day and a neuroscientist or neurologist or some Alzheimer's authority another day to get his questions answered. He can time it to match up with the Longest day fundraiser day: thelongestday.alz.org or Seth's annual Hilarity for Charity event.
