toasty (my inspiration at lunch)

"would you like your usual cheese and ham toasty today?"

"I hate that toasty..."

"hmm? what would you like instead?"

"I'll have a ham and cheese toasty."

"aren't they the same?"

"one is cheese and ham, one is ham and cheese."

"I'll do you one of each, and if you can tell the difference you don't have to pay."

"if I can't?"

"you pay for both."

...

"which is which?"

"both are cheese and ham, I don't want either of them."
