Mable

Rod was out having a meal with his friend Mable,

Mable slowly slipped down her chair and under the table.

Rod seemed calm and unaware that Mable had disappeared,

Concerned about Mable's welfare the waitress interfered.

"Pardon me sir,I believe your wife has just disappeared under the table"!

"No my wife has just walked in,this is my girlfriend and she's called Mable."
