What, in your opinion, is a great B-side (of a 7 inch vinyl record)?

I was watching a documentary on 7 inch records this evening, and “the b-sides” were also discussed in it.
That made me think what, from my small collection of singles, was the best b-side that I have.
The b-side of The Cult’s Love Removal Machine must be it: Wolf Child’s Blues it’s called.
What, for you, is the best/a great “other side” of a single that you have/had?
