It all started with "First Kiss," a now viral video featuring couples meeting and then quickly locking licks. Turns out the clip, which has received over 47 million views on YouTube and counting, is fake and actually an advertisement for Wren Studio. The 20 "strangers" are actually actors and models, but that hasn't stopped the brilliant parodies.
For example, "First Sniff" is an adorable honest look at canines sharing precious moments together.
But Jimmy Fallon took it one step further with the animal stars.
"We used puppies and kittens, I think it came out pretty well," Fallon revealed on Thursday's Tonight Show about "First Lick."
