Four-wheeled thinking

Limiting yourself to what you know. The opposite of "thinking outside the box".
Originating from transportation, automatically thinking you need to use a car to get to your destination; where instead you could use a motorbike, train, tram, bus, scooter, or any number of vehicles that have less or more than four wheels.

Four thumbs

When you type so fast it looks like you have 4 thumbs
Like in anime/manga, they put multiple fingers to show the speed of the characters typing (with an addition of movement symbols like "《" "//" "=" ect...)

Person 1: typing
Person 2: "do you have Four thumbs or summ"
