The baby is great. My wife and I have just started potty training. Which I think is important, because when we want to potty train the baby we should set an example.

The line is a piece of self-deprecating, absurdist parenting humor. Mandel begins with a conventional celebrity update—praising the baby and mentioning potty training—then pivots to a comic reversal: the parents, not the child, are the ones being “potty trained” to “set an example.” The joke plays on the earnest language of childrearing advice and the cultural expectation that parents model good behavior, exaggerating it into a literal, bodily scenario. It also reflects Mandel’s stand-up persona, which often mines everyday domestic life for awkwardness and turns it into a punchline through misdirection and escalation.
