Years ago the University of Wisconsin-Milwaukee instituted a free bus to cut down on the number of student parking stickers, since so little parking was available. This was quite successful, and was later integrated into Milwaukee's excellent public transit service. This effort (c.1975) was based on a well-known Oxford poem "What is this that roareth thus?/ Can it be a motor bus?/ Yes, the roar and hideous hum/ indicat motorem bum..." The age of that poem is indicated by the now obsolete term motor bus, itself an abbreviation for motor omnibus lit. "a mover for all." Such verse, mixing classical and vernacular languages, is known as macaronic.
At ten to eight I start to fuss:
"Where, oh where, is that Ubus?"
"I prithee, Ube, come in haste;
No college egghead has time to waste.
At last I see the Ubum coming -
Wheels a-whirring, engine humming.
The Ubi portals open wide -
What a squash I see inside!
No sticker sticker will ever know
The togetherness in that Ubo. Yet with it all my spirits are high,
'Cos anti-polluting are these Ubi.
We're saving smoke and smog and cash
As into Ubos we blithely dash.
No nature freak has a better forum
Than the wriggling interior of these blessed Uborum;
And East Side now will dwell in peace,
Served by swarms of swift Ubis.
