I will give Tom Batiuk this, he rarely reuses artwork. Story arcs, dialogue, themes, comic book references, potentially fatal diseases, and whatnot, sure… but not artwork. No, he loves redrawing Act I scenes in his current “realistic” style.
Lisa appears less desperate in the 2017 panel than she did in 1985, though one could say she appeared Les desperate in 1985… On the Funky Winkerbean retcon scale this is RETCON NINETY-FIVE. Today’s strip hits RETCON ONE in panel 3, though.
Les, who alleges that he was so in love with Lisa back when this happened, actually asked three other girls to prom before he asked her: Cindy, who Les files a sex discrimination suit against after she turns him down; Allison, who Les asks via world’s worst wingman Crazy Harry; and Tracy, who Les openly insults before asking.
Oh, and he doesn’t appear to know or remember Lisa’s name until after they dance, (in some pre-prom dance in the gym that they are both attending? I can’t quite figure out what is going on.) referring to her as “that girl” in his thoughts before asking her to dance.
