Any fun gender reveal games or ideas? :)

I'm doing a gender reveal with my family, the theme will be winnie the pooh. I thought of having the guests sign or write short messages in one of the pooh books. I saw some ideas like have the guests vote on the old wives tales, baby taboo game. Anyone has ideas on games, prizes? I have to arrange for 2-3 activities or its gonna get awkward during the gathering.. :P
