John Melendez, who became famous as Howard Stern sidekick "Stuttering John," got the president to call him back from Air Force One after posing as New Jersey Sen. Bob Menendez. Melendez played the prank call on his podcast. The screw-up has left the White House scrambling to figure out how Trump ended up placing the call, especially since his legislative team tried to kill the call in advance after learning that the U.S. senator wasn't trying to reach the president. "Stuttering John" was a prominent part of The Howard Stern Show for 16 years, famous for his ambush celebrity interviews. In 2003, he competed on the ABC reality show I'm a Celebrity...Get Me Out of Here!, which led to a guest spot on The Tonight Show. Based on that appearance, Leno hired Melendez as his announcer in 2004, which angered Stern and resulted in a years-long feud between the shock jock and Leno. Melendez worked for Leno until his Tonight Show ended in 2014.
