I'll also add other things that make me laugh starting with each letter.
Letter I is for Indiana Jones, one of my favorite franchises growing up. Then they made the fourth movie and--well, I'll stop right here. I want this to be humorous, but bad movie making is not a joke. Anyway, this one was put together by Aaron Shimbeck. Thanks, man!! (He also did the one for the letter F)
Other things that start with I that make me laugh:
I is for how I start to dance every time I hear the words, "I like big butts..." comes on. This cracked me up, if you catch all the window nuances.
I is for Ice Cream, and how I wish I had a little kid so I could pull this on him.
I is for Introverts, because we rule!!! (By ourselves, ideally)
I is for Irony. Another irony? Did you know that irons are not made from iron? That makes them not only ironic, but non-ironic as well.
I is for when people told me "there is no 'i' in team," and I would respond, "Yeah, but there sure is one in win!" Well, this would have been even more clever.
I is for Darth Vader realizing what Boba Fett was really saying.
I is for all the iApple products out there.
I is for... well, IDK. This:
I is for trippy Illusions. I didn't even need to lace this with LSD or anything!
I is for the lack of Instruction manuals that come with kids.
I is for Intelligence, and the benefits at work when you have it.
I is for Intelligence, and the detriments at work when you lack it.
I is for Internet Explorer. It may get a bad rep, but admit it, it is by far the best browser to download other Internet browsers.
Which leads to I for the Internet, plus further proof that Egypt was way ahead of their time.
I is for Introverts again. I was going to put something about eye = 'I', but I think this is fine.
I is for Irony again, and it's Imitations of art.
I is for one of the most iconic lines from Star Wars. I'll just let you figure it out.
