Joe hope question would've been good if he asked them that before the pod, told them to think about it and then brought it up again on the pod.
He had time to think about something outside the box and something outside of kids/family but then springs it on them and get annoyed they can't/won't come up with something he finds different/entertaining enough in quick fashion for a podcast.
Joe is being a moody fakkit because his doctor told him to stop smoking. That and because Ish isn't there for him to pick with.
