Things that are 1000 times funnier when your kid laughs at them

Seriously why is a simple fart noise the most hilarious thing in the universe to a 4 year old? I'm over here looking stupid making fart noises and my son is literally crying laughing. Then my wife gives me that look like I'm the worst influence but honestly those moments are gold. The simplest dumb stuff becomes legendary when you see that joy on their face.
