Universal Solvent
A little old lady was visiting a big science exhibition and came upon
a group of boffins in white coats around a big vat of
bubbling liquid and asked, “What are you doing?”
One of them replied “We are seeking a Universal Solvent”
“What’s that?”
“Well, we wouldn’t expect someone like you to understand that” they sneered.
“It is a liquid in which everything will dissolve”
“Oh!” She said “What are you going to keep it in?”
