Starting a Zoo

[rebbonk]

I was thinking of starting up a small zoo, so I wrote a letter to Dudley Zoo: ‘Dear sir, I’m starting up a zoo, can you please send me two mongooses.’

I thought that didn’t sound right, so I tried again: ‘Dear sir, I’m starting up a small zoo, please send me two mongeese.’

Nope, that still didn’t sound right. ‘Dear sir, I’m starting up a small zoo, please send me two Mongi.’

‘Ahh, s*d it,’ I thought. 'Dear sir, I’m starting up a small zoo, please send me a mongoose.

P.S.

Spoiler:

please send me another one.’
