I'm not a big peanut butter person, but I do like a good PB&J and I do like to dip a Hershey's bar into a jar of peanut butter once in a while. Sometimes Reese's just doesn't cut it and I need the real thing. :p
When I was younger I ate it straight out of the jar, though I didn't pull a Puck ("The Real World: San Fransisco" reference) and use my fingers.
"I still need to try Marmite and Vegemite to see the appeal." - If you like the smell of yeast in a bakery and the taste of salty things you might like them. It's definitely an acquired taste. VERY strong. I like Vegemite, though I haven't had it in years.
