Johnny, if you want to post or pm your address, I will send you a jar of Vegemite. You have shared many wisdoms here and Getbig is in your debt.
It's disgusting stuff. From the first bite you'll throw the toast and the jar in the trash. Then, out of nowhere, 3-4 days later, you'll get struck with a craving for it. Interesting substance.
Also try it with some melted low-grade cheddar cheese on the toast while listening to ACDC.
