Jon Hamm ended up crashing Jimmy Fallon’s “Tonight Show” monologue on Tuesday as he kicked off his appearance by taking part in a hilarious skit.
Hamm, 47, pretended to be Fallon’s high school English teacher, with him donning a plaid blazer and curly wig to take on the role.
However, there was no fooling Fallon, 43, who straight away told him he was not his teacher and was actually the Emmy Award-winning actor, Jon Hamm.
Fallon began the sketch by saying, “Let’s get to some sports news, I saw that a new report from the American Gaming Association found that this year alone Americans spent over $10 billion gambling on the March Madness tournament.”
Hamm then chipped in from the side of the stage, “Well, let me tell you, that’s a real shame pal,” before he added: “I’m sorry to interrupt, I just wanted to rap about some stuff out loud with you man.”
He also said, when Fallon reminded him of who he was: “No-cares it’s fine. I don’t know who I am Jimmy. I’m just someone who believes in you.”
The hilarious clip ended with Fallon insisting that his teacher would “always be in here,” with the host attempting not to laugh while pointing to his heart.
Hamm’s “Tonight Show” appearance also saw him open up about golfing with Ray Romano, as well as discussing what life was like as an eighth-grade acting and improv teacher.
