Christmas were coming,

And the teacher was asking the students how they imagined Santa Claus.
The teacher asked Mary how she had Santa Claus in her mind, and Mary said "He's fat, with a thick beard". Then Bobos wanted to say his opinion but the teacher knew he would say something not nice so she didn't choose him.
After the whole class had said how they imagined Santa Claus, there were a few minutes left before the class was over, so the teacher asked Bobos how he imagined Santa Claus.
Bobos said: "To me, Santa Claus is a big A$$"
The school bell rang at that moment and everyone left, except for Bobos because his teacher told him to wait.
The teacher asked him, "Why the heck did you just say that Santa Claus is a big a$$?!"
Bobos replied, "Because when I asked my dad what Santa Claus is bringing me this year, he said $hit".

 

xDDD
that's a great joke...not much else to say.
