This is incredible. Some brace, diligent and genius soul going by the YouTube name of koonjam actually came up with and followed through on the idea of compiling every single grunt noise that Tim Allen and the rest of the cast made on Home Improvement. From Allen's trademark 'Eeuugghh?' (which is the best phonetic description we can make) to the general gorilla grunts and such, we never actually realised how much of Home Improvement was actually just people making animal sounds.

The best part is watching the kids age from wee whipper-snappers all the way to actual people. That and the cringe '90s fashion.

Turns out Buzz Lightyear was merely a caveman in disguise all along.
