I made the important discovery that gnocchi is not pronounced 'knocky' as I thought (or, if dining with an attractive companion, amusingly mispronounced 'nookie') but 'nyocky'.
Next time I eat Italian I shall impress the socks off the waiter by asking for nyocky and brusketta, and express my approval of the meal by pressing my index finger to my cheek and twiddling it.
Unless I'm in Pizza Hut, perhaps.
