YELLOW CARD

[Jean Genie]

Thanks very much to all! But that was cheating -should it not have read 'dessert' vehicle?

[Baldric]

//If with small insertion// small + 'S' inserted

[factor-fiction]

Desert with an s (small) inserted = dessert

[Baldric]

small = s inserted, not +

[lckay]

I thought it was Street Trolley reduced to St Trolley (vehicle) with wee (small) inserted. Assumed desert was an error and should have been dessert.

[Baldric]

They don't make that many errors

I'm sure you're right but when you can't make sense of an answer is easier to blame the compiler! :)
