The spot, created by Supernatural, shows the travel search engine might seem too good to be true.
Travel search engine Kayak can search hundreds of travel sites for the best deals, but not everyone is convinced.
In the spot "Mom's a Kayak Denier," a woman brings her boyfriend home to meet her parents.
"Remember, Mom is a Kayak denier, so please don’t bring it up," she says.
Unfortunately, mom hears the word "Kayak," and tells her daughter’s boyfriend, "Do the research, Todd!"
When he tries to explain how Kayak works, mom screams, "They’re lying to you!" She storms away from the table, urging him to "Open your eyes."
