Innocently Insensitive: Mr. Bean frequently veers into this, particularly where his girlfriend is involved. Special mention to "Merry Christmas, Mr. Bean", where he asks her what she wanted for Christmas and she points to an engagement ring in a store window. Unfortunately, Mr. Bean mistakes her gesture for pointing to the portrait behind the ring and buys that instead. This leads to Irma tearfully running out on him during their Christmas evening together and a Bean, who seemed quite proud of himself for getting her what he thought she asked for, commenting in a hurt tone of voice, "W... what was wrong with it?"
Manchild: He sleeps with a teddy bear. In the first episode, he puts two dolls on the table when he sits down to take an examination. In general he is of the more common, Fish out of Water type, although his strangeness goes beyond childlike and into the realm of truly bizarre.
In the fourth season of the animated series, he started speaking in complete sentences.
Unsympathetic Comedy Protagonist: Subverted. Much of the time he's a borderline sociopath, but there's plenty of moments that show that there's a real heart underneath all the madness.
Walking Techbane: Or at least, when he's dressed. Unless he's naked, he completely screws up tv signals and tends to break stuff or cause unexpected effects.
Companion Cube: Bean treats Teddy as if a four-year-old would treat a teddy, and it's both hilarious and ridiculously cute.
Drives Like Crazy: Especially in the episode The Trouble with Mr. Bean where he dresses in the car while driving himself to the dentist, and Do It Yourself Mr. Bean where he drives on the roof of the car after stuffing the inside full of things he bought.
Free Wheel: Occurs every time he drives his car and meets up with the Reliant (see below)
