Heaven has a countably infinite number of cloud for people to stay, each of which has a good soul living on it.
A countably infinite number of infinite universes are extinguished by God (their beta period had expired). So, a countably infinite number of groups of good souls (each of which are countably infinite in size) were knocking on the doors of heaven. Each person, in each group was carrying a little ticket, from $\ge 1$ (which one receives before passing the pearly gates).
How will God and his dear mother accomodate all these people on a cloud of their own without creating any new clouds?
