PE Teacher and pupil jokes

PE TEACHER: Why didn't you do the long jump?
PUPILS: Because I'm short sighted, sir.
 
PE TEACHER: Why are you swimming on your back?
PUPIL: Because I've just had lunch and it's dangerous to swim on a full stomach.

PE TEACHER: You never come first in anything.
PUPIL: I'm always first in the dinner queue.
 
PE TEACHER: Why didn't you attempt the high jump?
PUPIL: I'm scared of heights, sir.
