Freudian slip, illiteracy, or just a gift for people with a love of irony?

Buried in a news story on NPR, National Public Radio, I found a paragraph that kept me laughing for several hours. I didn't laugh about the allegation of voter fraud by a public figure who has baselessly cried "Election fraud!" against the massive evidence of audits and failed lawsuits, but because this attorney is so sure of his own perfection that he didn't proofread his own official documents submitted to a court, nor did he task a member of his law firm with checking his copy. 

Here's the section that amused me. 

"In the weeks after the [2020] November presidential election, [Lin] Wood was one of the most prominent voices spreading misinformation about the nation's vote-counting process, filing several failed lawsuits seeking to toss out millions of votes and block Joe Biden from becoming the next president.

"In one suit, the defamation lawyer ... accidentally wrote his lawsuit was filed under "plenty" of perjury instead of "penalty," and attempted to push debunked claims of fraud all the way to the Supreme Court."

A lawyer promising plenty of perjury. It must be a first!
