A popular pun involving the word “wasabi” is:
 
Q: What did the sushi say to be bee?
A: Wasabi (What’s up, bee).
 
The joke has been cited in print since at least 2007.
 
   
Wikipedia: Wasabi
Wasabi (わさび（山葵）?, earlier 和佐比; Eutrema japonicum/“Wasabia japonica”) is a plant of the Brassicaceae family, which includes cabbages, horseradish, and mustard. It is also called Japanese horseradish, although horseradish is a different plant (which is generally used as a substitute for wasabi, due to the scarcity of the wasabi plant). Its stem is used as a condiment and has an extremely strong pungency more akin to hot mustard than the capsaicin in a chili pepper, producing vapours that stimulate the nasal passages more than the tongue. The plant grows naturally along stream beds in mountain river valleys in Japan. The two main cultivars in the marketplace are E. japonicum ‘Daruma’ and ‘Mazuma’, but there are many others. The origin of Wasabi cuisine has been clarified from the oldest historical records; it takes its rise in Nara prefecture.

Sacramento sushi chef Chris Jackson of the Mikuni family of Japanese restaurants deserves some kind of award for keeping his composure while giving a session on making sushi rolls. The demonstration was outside, in the middle of the Village at Northstar just outside Truckee, on a day so sunny and balmy hordes of bees decided to pay the festival a visit. Jackson, filling in for an ailing Kotaro “Taro” Arai, Mikuni’s executive sushi chef, gave a high-energy lesson with authority, intelligence and wit, and without losing his sense of humor, even after being stung twice by bees. “This reminds me of a joke,” said Jackson after getting stung. “What did the sushi say to the bee: ‘Wasabi!’” OK, so maybe you had to be there.
