Donald Trump
US Republican presidential candidate Donald Trump has run a campaign filled with bizarre momentsRandall Hill/Reuters

Many will have predicted that when billionaire tycoon Donald Trump announced he was going to run for US president, his campaign wouldn't be short of controversy. But few will have foreseen just how bizarre – and at times entertaining – the businessman has gone on to be.

From his views on Hillary Clinton's inability to please her husband to his attacks on the physical appearance of other women, here are Trump's top 10 quotes during his campaign so far – from the odd to the downright offensive.

1. On rival Republican candidate Carly Fiorina:

"Look at that face. Would anyone vote for that? Can you imagine that? The face of our next president? I mean, she's a woman, and I'm not supposed to say bad things, but really, folks, come on. Are we serious?"

2. On Hillary Clinton's presidential ambitions:

"If Hillary Clinton can't satisfy her husband what makes her think she can satisfy America?"

3. On the Chinese:

"I'm not saying they're stupid. I like China. I just sold an apartment for $15m. Am I supposed to dislike 'em? People say you don't like China. No, I love them. But their leaders are much smarter than our leaders. And we can't sustain ourselves with that. It's like, take the New England Patriots and Tom Brady and have them play your high school football team."

4. On Senator John McCain's war record:

"He's not a war hero. He was a war hero because he was captured. I like people who weren't captured."

5. On illegal Mexican immigrants:

"When Mexico sends its people, they're not sending their best. They're not sending you. They're not sending you. They're sending people that have lots of problems and they're bringing those problems with us. They're bringing drugs, they're bringing crime, they're rapists, and some, I assume, are good people."

...And on criticism from CNN's Don Lemon for those Mexican immigrant comments:

"All I'm doing is telling the truth. Someone's doing the raping, Don. Who's doing the raping? Who's doing the raping?"

6. On what will happen if he wins the US election:

"We will have so much winning if I get elected you may get bored with winning. Believe me. We are going to start winning big league."

7. On his solution to the illegal immigration problem:

"I will build a great wall – and nobody builds walls better than me, believe me – and I'll build them very inexpensively. I will build a great, great wall on our southern border, and I will make Mexico pay for that wall. Mark my words."

8. On the owner of Huffington Post, Arianna Huffington:

"Ariana Huffington is unattractive both inside and out. I fully understand why her former husband left her for a man – he made a good decision."

9. On rival candidates' electoral competence:

"Some of the candidates, they went in and didn't know the air conditioner didn't work and sweated like dogs, and they didn't know the room was too big because they didn't have anybody there. How are they going to beat Isis?"

10. And finally, on any "haters" out there doubting the man, Trump tweeted this to his five million followers:

"Sorry losers and haters, but my I.Q. is one of the highest – and you all know it! Please don't feel so stupid or insecure, it's not your fault."
