Encounter with a gym ball

Do you know what this is?

This is a gym ball

In a glance, it looks friendly and playful

But don't be fooled my friends

It's actually mean, cruel and evil

I shit you not

Nasty ball I tell you

Especially to an unfit person like me

Damn you ball!!

But mark my words ball

I will conquer you one day

I'll kick you in the ass like nobody's business

Wait...you don't have an ass

But I'll kick your ass anyway

We'll see who's gonna have the last laugh
