鬥拳

斗 = ⺀ + 十 : Mnemonic symbol: a 斗牛士 (dou4 niu2 shi4) is a matador, who will represent 斗 when used as component.

The matador (斗) and Don Quixote (d) are fighting (斗) in the outhouse's bathroom (ou4) about who may use the bathroom next. The matador yields a holy cross (十) as a weapon, while Don Quixote (d) wisely chose a blossom (⺀) to cushion the crosses' blows.

拳 = 关 + 手 : Cupid (qu) trains his fist (拳) in the anthill's kitchen (an2). He just started though, so he wants to start easy and just hits a baseball glove (手) he hung on the wall. Unfortunately he hung it right over the anthill's off-button (关) so that upon his first hit the lights go out.
