We quite enjoyed these contemporary irregular verb conjugations by McSweeney’s contributor Elizabeth Preston. For instance, the infinitive to smile:
Simple past: I smiled.
Present tense: I smize behind my mask.
Present progressive: I am squinting jovially and half-nodding at strangers on the sidewalk.
Future tense: I will miss this mask-acquired acne not one bit.
Future perfect: I will have forgotten how to smile without grimacing like a toddler who’s asked to say cheese.
