"I know a lovely walk," you should say, "across a quaint old
bridge." 

The rest is, of course, easy.  Arrived in the middle of the quaint
old bridge, which leads across a cavern some three hundred feet
deep, you should quickly seize the tall college graduate, and
push her, not too roughly or ungentlemanly, off the bridge. 

And, if you are really a genius, and not merely "one of the
crowd" you will return to the ballroom and, going up to the young
lady who was responsible for your having met the sweet girl from
South Orange, you will offer her your arm, and smile invitingly. 

"I know a lovely walk," you will say, "across a quaint old
bridge."
