A university student wanted to sit next to one of his teachers at lunch

However, the teacher looked at the student with an arrogant face and said:

'A swan shan't be friends with a pig.'

'Then I shall fly on,' answered the student with a smile.

The teacher was clearly vexed by the cheeky reply and decided to make sure to do everything in his power to fail the student at the exams.

At the oral exam, he gave the student the hardest questions, but the student had amazing answers for everything. Therefore, hoping he could still fail his victim, the teacher asked him a trickier question:

'You're walking on a road and you find two bags. One contains gold, the other cleverness. Which bag do you choose?'

'The gold.'

'Unfortunately, I don't agree. I'd choose cleverness, because that's more important than money.'

'Everyone would choose what they don't have,' says the student.

The teacher turns red, and he's so angry he writes "ass" on the student's paper. The student leaves without looking at the paper. However, he returns shortly, gives back his paper and says:

'Excuse me sir, you did sign my paper, but you forgot to give my grade!'
