We answer this question in the affirmative: it **is possible** to smear paint on the wall without creating a valid Perl program. We employ an empirical approach, using optical character recognition (OCR) software, which finds that merely 93% of paint splatters parse as valid Perl. We analyze the properties of paint-splatter Perl programs, and present seven examples of paint splatters which are not valid Perl programs.

I want him to splash in muddy puddles and smear paint on the walls and read novels under the covers way too late at night. I grew up too soon and wish I'd had more time to be a kid. Why do schools teach vocational skills so young these days?"
