Alfonso is reported to be trying to copyright the dance – which is often associated with the Tom Jones song It’s Not Unusual. He first performed it in a 1991 episode of the show.
‘Twenty-seven years later, The Dance remains distinctive, immediately recognisable, and inextricably linked to Ribeiro's identity, celebrity, and likeness,’ his lawsuit claims.
The star also reprised the dance during his 2014 stint on US Dancing with The Stars.
Alfonso isn’t exactly strapped for cash or desperately clutching at lost notoriety – he’s the current host of America’s Funniest Home Videos.
