Balls?

So today we had our chemistry class from 2 to 5 p.m. I can tell everyone was sleepy. It was at one point, at half past 4 when the teacher was explaining something about polarising power or whatever it was. Aneel being the Aneel he is, got the attention of teacher and something happened that kept me awake for the rest of the lecture. It was,

Teacher; Aneel I see you're so active today.
Aneel: (sleepy gay smile)
Teacher: Imagine Aneel a small ion with high polarising power, he can polarise, err (staring at me) the one beside him.
Aku: (smile ungayly)
Teacher: blah blah blah.. What'll happen to their balls?
Aku & Aneel: what?
(it is based on what we really heard)

there was also a time when:

Teacher: Imagine here you have some small red balls, and then you want to replace them with some much much larger balls.
Students: (blur)
Teacher: these are small balls, and you have a big one, how're you going to replace them?
