Some Say Marry Money But My Brother Says Big Boobs Matter More
Keeping the ones with same first letter straight can sometimes get confusing, but at least this way you cna remember the first letter, and usually that was enough of a recall hint for me to get the rest of it.
I'd seen the Old Olympus one, but it never stuck like the dirty one did. In fact, one of our 60 year old lady lab professors came to our tank during head/neck and told it to us, and all 4 of us kinda muttered and looked down and said "eh, that one's kinda tricky". She was ok with that and then asked "so what do you guys use?", and one of the guys in my group very diplomatically told her "it's umm, not real appropriate". She laughed and moved on. I'm sure she's heard them all before anyway, but it was kinda funny to see us look at each other deciding what to say...
