biological-clock

A five-panel comic. Panel 1: a dark-haired woman tells a man, "Bob! My biological clock is ticking!" Panel 2: she hopefully asks, "You... you mean you've changed your mind and you want to have a baby?" Bob replies, "No. I made a clock entirely out of living flesh." Panel 3: Bob proclaims, "Behold!" Panel 4: a huge, robed, faceless figure made of red living flesh towers over the tiny silhouettes of Bob and the woman. Panel 5: the woman says, "I'd still like to have children," and Bob answers, "I just don't think we have the time for that." Votey: a close-up on the monstrous flesh-clock creature's face while Bob adds, "Also, the lawsuits are gonna cost a fortune." The joke turns the idiom "biological clock" literal: instead of agreeing to kids, Bob has built a horrifying living clock-monster that now consumes their time.
