An Englishman, a Mexican and a Kurd...

went into a garden...

G, my Mexican (ex-)colleague, invited us all to a party at his, on the grounds that British people don't celebrate enough. To entice us, he said that N had agreed to do some Morris dancing. I was incredulous and asked G whether N really was going to dance. 
'Yes,' said G. 
I didn't believe him. 'And he's agreed?' 
'Of course.'
I still didn't believe him. 'OK, in that case I'll bring my fiddle and I'll play the music. I'm no good, but I'll play anyway.'
G's turn to be incredulous. 'Well, I'd better ask him then.'

And he did, and invited a real Morris dancer to bring the kit and teach those who wanted to learn, as well as two much better musicians to help me out.
