Maths class and the teacher asks the class a question

'Children, how many pigeons will we have when there are three of them sitting on a branch and we shoot one?'

Little Johnny raises his hand eagerly.

'None, of course.'

'What do you mean, none?' asks Miss Carpenter, the teacher.

'Because if we shoot one, the rest will get scared and they'll all fly away.'

'Oh, I really like the way your mind works, but that's not the answer I was expecting, because mathematically speaking two pigeons will be left sitting on that branch.'

The class continues. Towards the end, a few minutes before the bell rings, Little Johnny raises his hand again.

'Miss Carpenter, could I ask a question as well?'

'Of course, dear.'

'Three women are walking on the street. All three of them are eating ice cream: the first one is licking it, the second one is biting it, and the third one is sucking it. According to you, Miss Carpenter, which one is married?'

The teacher blushes, but answers all the same.

'I'd say the one who's sucking the ice cream' says Miss Carpenter.

'Well, I'd say the one who's got a wedding ring, but I really like the way your mind works.'
