喜极而泣

极 = 及 + 木 : As Joan of Arc (ji) and Yuwen Huaji (及) pass over the north pole (及) at Christmas just inside the space station's entrance (Ø2) they decide to celebrate this moment by having a little contest. Between them there is a rather large Christmas tree (木) and they decide that whoever climbs to its top (极) first is the winner.

而 = 𦉫 + 丆 : A comb. Albert Einstein is getting ready to go out just inside the entrance of the space station. He put up some loud music on the stereo and tries to comb his hair with his comb and the help of a wind wheel.
