The Moveysavingexpert.com pioneer was on hand to reveal how This Morning viewers could save thousands by opening a LISA.
The 55-year-old groaned: “ISA, LISA… Schiesser.”
Naturally, Phillip’s sudden outburst caused Holly Willoughby to erupt into a fit of giggles.
And she wasn’t the only one, as This Morning viewers were all in hysterics on Twitter.
“Lisa…..isa….might aswel be speaking German to me…..pretty sure Phil just did (naughty lol) I’d rather just stay poor, haven’t got time to work this out #thismorning,” teased one fan.
Another chuckled: “Oh phil you crack me up @Schofe #shisa #thismorning #theschofe.”
“ISA LISA SHISA #ThisMorning , think you got away with that one Scoey,” mused a third.
“Scheisse. Omg @Schofe #ThisMorning,” posted one more, which was followed by: “Scheisse? a thought echoed by thousands of viewers #thismorning.”
The hilarity came during an eventful This Morning today as the show opened with an epic blunder during a crucial weather update.
As The Beast from the East showers snow across the nation, This Morning weather reporter Becky Mantin was left aghast without her clicker.
Fortunately for the reporter, those working in the gallery helped her get through the report with ease.
“Cue, there it is,” she exclaimed as the maps changed without issue. “I didn’t even need a clicker!”
The Strictly Come Dancing star delighted viewers as galloped around a Texas ranch to share details of the £250,000 competition.
This Morning airs weekdays at 10.30am on ITV.
