“Korma” should not be confused with “coma,” but there are jokes. A pun about spicy Asian food is:
 
A man overdosed on curry powder and went into a korma.”
 
“Did you hear about the man who overdosed on curry powder and slipped into a Korma?” was posted on alt.tasteless.jokes on February 11, 1995.
   
“Two junkies accidentally snort curry powder instead of cocaine. One’s now in a korma, the other’s got a dodgy tikka” is a related joke from about 2007.
   
     
Wikipedia: Korma
Korma (from Turkish kavurma), also spelled kormaa, qorma, khorma, kurma, or qovurma, is a dish originating in South Asia consisting of meat or vegetables braised in a spiced sauce made with yogurt, cream, nut or seed paste.
