Olive oil probiotics
What, never heard of these?
Thats because i just invented them, heres how:
Keep a litre bottle of olive oil in your desk drawer;
Pour over lunch or swig straight from the bottle at mealtimes;
Go on business trip for 5 weeks;
Return to desk, buy lunch, pour oil over lunch; eat lunch;
Examine spout of olive oil bottle - discover new species of bacteria - urrgh!; Feel very ill, perhaps only psycologically.
Perhaps best not to swig and leave salivary bacteria to grow unchecked...
