Magic beans

A wizard gave Jack magic beans

In exchange for his cow, by all means. 

Jack pondered the trade

Feeling somewhat dismayed,

'Did I swap my poor cow for just dreams?' 

Rainproof spell

 A wizard at the bus stop did stand

'Neath a dome conjured by his own hand.

While the rain poured down fast

He stayed dry to the last

And the commuters got soaked - all unplanned.
