My New Colander

I bought a brand-new colander
‘Cause mine was at its end.
I’ll bet you think that there’s an error
In the word I’ve penned.

But though I also purchased
(A coincidence, but true)
A calendar today, a fresh new
Colander was due.

The old one fell apart; I hope
The new one does the trick.
To those of you who thought I goofed,
I guess you’re not so slick!
