In an increasingly blasé world, it can be reassuring to know that some people have maintained a sense of wonder for the simple things — especially when those moments are captured on camera.
Paul "Bear" Vasquez kicked off the trend after video of the enthusiastic California man crying over the sight of a double rainbow went viral in 2010. To date, the video has racked up nearly 35 million views and achieved "classic" status among viral video purists.
More recently, a New York train lover uploaded footage of his encounter with a 1953 EA heritage train:
Informally dubbed "Double Trainbow," the video is a two-and-a-half-minute expression of the North Creek man's unbridled passion for the vintage vehicle.
And don't even get him started on the horn.
While there's some debate about whether the video is genuine or a parody of the infamous Double Rainbow clip, the display of sheer emotion has struck a nerve among YouTube's seen-it-all community.
While there were some obvious cracks about the man's level of enthusiasm, most commenters lauded the train lover for the ability to express such a pure moment of joy.
Of course, that didn't stop the barrage of inevitable jokes.
"Someone just walked by my office while I was watching this......porn would've been easier to explain," cracked YouTube member Steve Rix.
