Tim Cook replaced his surname on Twitter with an emoji of Apple company logo.
On Wednesday while addressing an inaugural meeting of the American Workforce Policy Advisory Board at the White House, Trump said, "I used to say, 'Tim, you've got to start doing it over here,' and you really have. You really put a big investment in our country. We appreciate it very much, Tim Apple."
All this while, Tim Cook was sitting right next to Trump.
The video soon went viral sparking a row of hilarious memes on social media.
However, as Tim Cook embraced his new name, the logo was only visible to Apple users. To Android and Windows users, a blank or grey square was appearing.
The reason for this is that Apple company logo is a private use area character of the American Standard Code for Information Interchange (ASCII) which is a character encoding standard for electronic communication that is supported on iOS and macOS only.
This is not the first time Trump has goofed-up someone's last name with the name of the company they were associated with.
Last year, he referred to aerospace and defence giant Lockheed Martin's CEO Marilyn Hewson as "Marilyn Lockheed."
