I think its Sam from Supernatural on the episode where he lost his shoe after losing a lucky charm and is now yelling insults at a bush...

ITS A HOBO. Hi mister hobo

A sperm trying to get up the stairs to an orange, who is also his lover, when suddenly, his wife EGG APPEARS

Its a princess taco

A fish jumping out of its bowl to get a piece of popcorn

Floating balls

Evil scientist Einstein who has stayed up way too many times

The lemon isn't having fun but is sarcastically saying he is

A zombie John Watson

Superman dropped his hot cocoa

Its a kitty type thing

A zombie Sherlock Holmes
