Reason for not going to the gym

I didn't go to the gym today.

The escalator there was not working.

Astronomy pun

I just had a trip to the International Space Station.

All I can do now, is stare at the astronomical bill.

Physics pun

In my physics class, I was asked, "What's the lowest temperature that's ever possible?"

My knowledge on this topic was Absolute Zero.

Misunderstanding pun

In our astronomy class, we were asked to write an essay on Mars.

I thought to myself, "How the fuck did they manage to sponsor our space travel?"

Mathematical Pun 4

I never borrow anything.

That's why I suck at subtracting numbers.

Seal pun

I was breaking a seal at work today when a colleague said, "How the fuck did you bring this animal from Antarctica?"

Geometry pun 2

The contents of my geometry box always helps me to defend myself from my enemies.

It's my protractor

What makes me happy?

I’ve finally found out what makes me happy.

Seritonin and Dopamine molecules...

Programming pun

I hate programming in C.

It has no class.

Geometry Pun

My father took me to the doctor because I had the uncanny ability to stand perpendicular at any inclination.

The doctor said that I was normal.
