So, do butterflies get humans in their stomachs when they're nervous?

[vasectomyfail]

but WHY does seeing your crush make you nervous? you'd think your body would give you some sort of stimulus that makes you more suave, flirty and confident so that you can easily breed. instead you become a stuttering sweaty mumbling mess.

Because I shouldn’t have eaten those genetically modified caterpillars alive...

These nervous systems must be a mess in people with anxiety disorders. Probably the reason behind a lot of the common symptoms with anxiety/depression/panic

"Bear sized Hyenas" eh? Whelp, thanks for that fresh tank of Nightmare Fuel. I can always count on YouTube...

[PierceArner]

That was a brilliant delivery. Thanks as always for this fantastic content!

[christophermolitor]

That well-timed “badly” killed me. I actually burst out laughing. Hank do you know you’re as funny as you are, cause your comedic delivery is one in a million. Thanks for the laugh.

"Are you nervous?"
"No, not at all. But the butterflies in my stomach are puking their brains out."

[panthleo]

Why do our legs feel weak and faded when we're scared? How does that make any sense from an evolutionary stand point? If it stops you from, you know, actually be able to runaway or defend yourself.

In a stressful situation just remember:" Evolution prepared you for this moment ... badly."

I've never really understood the expression on a literal level. When I was young I learned that the expression meant 'nervous' but I've never felt anything that I would describe as being similar to a sensation of actual butterflies.
