Mnemonic symbol: "Giga" apparently stems from a Greek word for "giant", so I'll represent 吉 by a giant.
The giant (吉) just entered the space station's kitchen (Ø2) and is very hungry. In each hand he holds Joan of Arc (ji) and the bachelor (士) captive and robs them for their mandarins (口) which he longs for.
Marilyn Monroe and the mean crocodile celebrate Christmas with a Christmas tree inside of the space station. Coincidentally they got each other the same present: each of them is giving the other one a sack of rice.
