Puns needed

I need puns about the life and work of Robert Burns and maths, and ideally dynamical systems. I feel it would be poor form to steal all my jokes from the Klein Four Group or Tom Lehrer*. It's a tall order, but I know you guys can do it - come on, ExoBrain, do your stuff!

Which is to say...

Weejies: we're having a Burns supper tomorrow evening, from around eight. You're invited. Let me know if you're coming and preferences for veggie or real haggis.

* I think of great Lobachevsky and I get idea, ha ha!
