I, for one, cannot stand peanut butter (the smell makes me want to puke). However, every morning I cheerfully make my g/f a PB&J to the folllowing specification:
2 slices Wonder sandwich bread
Using butter knife, apply thin layer PB to each slice, taking care to minimize bread tear
Using a different butter knife, stab jelly repeatedly to break up concentrated "gelled mass"
Using same knife, scoop jelly out of jar and drop on bread, taking care to avoid getting PB on knife
Once enough jelly is on each slice, spread to cover entire slice over PB
Press 2 slices of bread together
Put in Ziploc(tm)-brand sandwich bag
No muss, no fuss, no peanut butter in the jelly jar, no jelly in the peanut butter jar, and hopefully no torn bread mess.
