The Five Worst Ashton Kutcher Twitter Knock Knock Jokes

Ashton Kutcher at the Human Rights Watch Voices For Justice Dinner

Ashton Kutcher has been entertaining audiences since his first on-screen appearance as Michael Kelso on the popular sitcom, That ’70s Show.  Kutcher quickly became known for his ability to evoke laughter in viewers and while still a member of That ’70s’ cast,  he began his own hidden camera practical-joke show on MTV, called Punk’d.  The show, which focused on pulling pranks on celebrities, became a hit immediately after its first season.  It appeared that when it came to being funny, Ashton Kutcher couldn’t lose.  Unfortunately, everyone does not posses Kutcher’s same knack for humor.  Several Twitter users have come up with knock knock jokes that feature Kutcher as the punch line; however, many of the jokes are simply not funny.  Although Kutcher would probably be flattered by some of these jokes, he probably won’t be retelling any of them.  Here are five of the worst Ashton Kutcher knock knock jokes on Twitter.

This failed attempt at a knock-knock joke is a prime example of what happens when keeping it simple goes wrong.

This joke might actually be funny if it made sense, but unfortunately the level of thinking required to find the connection between Ashton Kutcher and came kills any potential the joke may have had.

Knock, knock? Who's there? Ashton Kutcher. Ashton Kutcher, who? That's what we should've been saying all along!

This joke would be funny if Ashton Kutcher wasn’t ridiculously famous.  Even if you don’t know (or like) him from his on-screen roles, chances are you’ve at least heard of him because of his relationship with Demi Moore which lasted from 2003 until their divorce in 2013.

Putting a new spin on an old jokes always comes with risks. Judging by the number of ha’s at the end of this tweet, it’s safe to say that @Samantha_Pair definitely miscalculated the joke’s potential.

Everyone should take a moment of silence and be thankful that Punk’d was at least 10 times funnier than this joke.
