I used to be good with kids, but as I get older, I’m grumpy and terrible with them. As for doing a gig at a 6-year old’s birthday party, you couldn’t pay me enough.

In this self-deprecating remark, Vegas plays on the contrast between an entertainer’s presumed ease with children and the reality of aging, fatigue, and diminishing patience. The humor comes from bluntly admitting a loss of warmth—“grumpy and terrible”—and then escalating it into an absolute refusal: even money can’t compensate for the ordeal of performing at a small child’s birthday party. Beyond the joke, the line gestures at how public-facing work can demand emotional labor (cheerfulness, tolerance, high energy) that becomes harder to supply over time, and how comedians often turn personal irritability into a comic persona.
