Saying “I’m Keith Hernandez” is still worth a lot of money.

The former Mets great had a few lines in a few “Seinfeld” episodes — and he’s still cashing royalties checks.

Hernandez starred in “The Boyfriend: Part 1″ and “The Boyfriend: Part 2,” then came back for the series finale in 1998. Hernandez said he gets paid every time the episodes air.

“So I’m going to say I get a check every month,” he recently told NJ.com. “Nothing less than six weeks. They show it all the time. It’s international and everything.

“It used to be almost $1,000. It diminishes as the years go by. So it gives me around $3,000 per year. I’ll take it. For doing nothing. So you can imagine what Jerry gets. The principal actors, what they get.”
