A strong relationship is built on many things: trust, shared values, emotional connection, and mutual respect. But for many people, being intellectually compatible matters too. Sometimes a lack of common sense can turn even the sweetest romance into an endless comedy show.

A Reddit user, u/Known-Pop-8355, asked people to share their funniest “I’m dating an idiot” moments, and the internet delivered. Here are some of the most hilarious stories from the discussion.

1. One woman’s jealous girlfriend once burst into a restaurant after seeing her eating lunch with an older woman. She caused a huge scene, accusing the woman of being her secret lover.

When the yelling finally stopped, the woman calmly said:

“Mom, this is my ex-girlfriend.”

Her mother still laughs about it years later.

The author of the thread later admitted that intellectual compatibility is important in relationships, though they believe patience and communication can overcome many differences.

2. A woman mentioned she wanted to learn Italian, and the guy she was dating laughed and said:

“Why? Italian is easy.”

When she asked why, he confidently explained:

“Italian is just American with an accent.”

He genuinely believed Italians spoke English dramatically. She laughed so hard she nearly cried, while he got offended.

3. One Redditor explained plate tectonics to his girlfriend during a museum visit. She refused to believe continents move and thought he was inventing nonsense.

Even after reading an entire museum display about it, she still insisted the museum had somehow created the exhibit to support his “lies.”

The thread creator also shared that controlling behavior — especially around money — is one of the biggest relationship red flags.

4. A woman remembered her ex-boyfriend intentionally flipping over glasses of water at restaurants so employees would have to clean the mess.

Years later, after unexpectedly meeting him again, he started insulting her and making rude comments about her child.

So before leaving, she recreated his favorite prank by flipping over a glass full of water and coins onto the table.

5. One woman called her boyfriend after he moved into his first apartment. He complained he couldn’t make tea because he didn’t own a kettle.

She suggested boiling water on the stove.

After a pause, he quietly asked:

“How?”

She ended up explaining to an adult man how to boil water in a pot. She later married him anyway.

6. A man dated a woman with two energetic dogs that needed daily exercise.

Instead of walking them, she drove them around because she believed riding in the car burned energy the same way exercise does.

The original poster later admitted that poor communication ruined one of their past relationships and emphasized how damaging it can be to bottle up emotions.

7. One user described their partner as impulsive rather than stupid.

After accidentally dropping a Skittle onto a bedsheet and seeing it stain the fabric, she immediately grabbed scissors and cut the damaged part out of the sheet.

Only afterward did she realize she had ruined the entire bedding set.

8. While watching skiing on TV, one woman argued it was impossible to know athletes were traveling at 100 km/h because the race only lasted a few minutes.

She also once asked:

“My aunt lives in London… is that near England?”

9. A man jokingly convinced a woman at a nightclub that he had legally changed his birthday to Flag Day because he loved the holiday so much.

She completely believed him.

Later, after performing a simple “coin behind the ear” trick, she became embarrassed and asked how long the object had supposedly been stuck in her hair.

That was apparently the moment he realized the date was over.

10. One woman briefly dated a mailman who constantly talked about becoming rich from his inventions.

His best idea?

Eye drops that would permanently eliminate the need for glasses.

When she pointed out that he himself wore glasses, he explained:

“The invention doesn’t exist yet.”

He believed that simply imagining the idea meant he deserved future profits if someone else eventually created it.
