Isaacs also frequently shares the deeply amusing and highly unusual requests he receives from the Harry Potter fandom. During a blazing hot, crowded convention signing, a female fan suddenly ripped open her shirt and asked him to sign her breasts. Stunned, Isaacs told her to stop because there were children present. The woman pointed out that the kids standing next to her were her own, and instead of being horrified, her children began chanting for him to sign them.
