Some thought Kimmel was poking fun at the Arizona Spring Break-friendly community by offering a free trip and a stay at the local Days Inn to whoever kept their Oscars speech the shortest.
Played off like a Price Is Right prize, Kimmel's opening monologue concluded with the reveal of Mirren showing off the jet ski, and it became a recurring bit throughout the show.
"Tonight we thank the moviegoing public", he said, which on this occasion, was a group of unsuspecting people "lured" into the TCL Chinese Theatre across the street from the awards ceremony, under the pretence of seeing the sci-fi movie Wrinkle In Time, starring Oprah Winfrey.
"Phantom Thread" costume designer Mark Bridges won both an Oscar and a Jet Ski at the 90th Academy Awards.
Turkish soldiers, 116 FSA militants killed in Afrin Operation
Late on Thursday, the Turkish military said eight Turkish soldiers had been killed and 13 injured in clashes in Afrin. PKK has fought for independence in South-Eastern Turkey since 1978 but the YPG has denied any links to the group.
Television viewership in general is declining, but Oscar ratings are often tied to the popularity of the movies that are celebrating, and this doesn't say much for "The Shape of Water", which won best picture on Sunday night.
Jimmy Kimmel has a clever trick up his sleeve this year to keep the show moving. But, as this year's shorter acceptance speeches showed, it tends to be the many packages and stunts that make awards shows like the Academy Awards run long, though outlier long speeches do contribute to the bloated runtime.
Kimmel announced at the end of the night that Bridges had the shortest speech, which clocked in around 30 seconds.
