英式橄欖球

英 = 艹 + 央 : Mnemonic symbol: a hero. An evil villain has been terrorizing the UK (英), so Maud Younger (y) and the hero (英) want to stop him. They know that he will visit engine later that day, so in front of the engine ((e)ng1) they prepare artificial lawn (艹) by adding a CPU (央) to each sheet. This way, each sheet acts as intelligent automated trap which will grab the villain once he steps on the sheet.

式 = 工 + 弋 : I'll use a specific style as mnemonic symbol: 哥特式, gothic.

Sherlock Holmes and the goth are celebrating a Viking festival in the space station's bathroom. They don't have trunks to throw around, so they use a steel beam. They also celebrate by practising archery. In zero gravity it is easy for them to set one world record after the next.

球 = 求 + 王 : Martin Luther King and the Queen of Hearts are playing with a globe beach ball in the outhouse's kitchen. They put a service request bell just between them and bounce their beach ball off of it with a loud "DING".
