【The Never Ending Love Story】

Throughout the course of her political career,The Never Ending Love Story Hillary Clinton has been routinely accused of one irredeemable sin: failing to smile.

From GOP chairman Reince Priebus to conservative commentator Dick Morris to an infinite parade of egg avatars on Twitter, everyone is deeply emotionally invested in getting the candidate to lighten up a little. She's running for president of the United States -- and a true commander in chief knows just how to lol.

It's time for Clinton to finally listen to the men who've told her to "smile" her whole life. Clinton has probably always wanted to smile and simply needed a strong man to teach her how.

So here are helpful lessons from some of her most incisive critics.

1. "This right here is the key to a successful smile." -- Reince Priebus

On Wednesday, Priebus went after Clinton for failing to smile during the 'Commander in Chief' forum.

"HillaryClinton was angry + defensive the entire time -- no smile and uncomfortable -- upset that she was caught wrongly sending our secrets," Priebus tweeted.

Now she can learn from a pro who has clearly mastered the genre.

2. "The best way to smile is to hide your bottom teeth and close your eyes very tight." -- Joe Scarborough

After Clinton won a major primary in March, MSNBChost Joe Scarborough decided the best way to congratulate her was by encouraging her to smile.

"Smile. You just had a big night," Scarborough wrote on Twitter.

Thanks for the pro tip, sexist Dad!

3. "Good smiles happen when you grin so hard all the blood in your body rushes to your nose." -- Mitt Romney

Last summer, former presidential candidate Mitt Romney warned voters that Clinton couldn't be trusted because she was too loyal to steamed milk.

"When you see her on a stage or when she comes into a room full of people, she's smiling with her mouth but her eyes say, 'Where's my latte?'" Romney said on MSNBC's "Morning Joe."

Only trust candidates whose eyes take their coffee black.

4. "Smile like you don't know the social media basics." -- Dick Morris

Political commentator Dick Morris accused Clinton of being unfit for the oval office because she showed too much emotion during a New Hampshire campaign event.

"I believe that there could well come a time when there is such a serious threat to the United States that she breaks down like that," Morris said. "I don't think she ought to be president."

Smile less, Hillary! No wait! Smile more! (Smile less?)

5. "Smile like you're a faceless, trolling hardboiled egg avatar."

During the Democratic National Convention, social media users pounced on Clinton for failing to smile. While the Daily Dot's list includes several well-known pundits, many of the criticisms were lobbed by cold, anonymous hardboiled egg avatars on Twitter: true masters of human emotion.

Smile like the egg avatars, former secretary of state.

6. "You don't have to smile if you wear a salmon-colored sweater on national television." -- Brit Hume

After Clinton won a big victory during the March primaries, Fox News' Brit Hume congratulated her not on her historical achievement, but on a much bigger victory: her smile.

Hillary actually smiled at the end of her speech. Mirabile Dictu!

It was a small step. But will Clinton ever truly learn how to smile like the masters above? Only time will tell.
