Announcement ideas


So my sister just found out shes pregnant with baby #2 and we are trying to think of a good lie to tell to get the rest of the family in the same spot to announce to them! Help! The only people who know right now are of course her, her husband, me, and her twin... We have 4 other siblings our parents and neice and nephews to tell. What would be a good unsuspecting way to get them all together to tell them? TIA
