Our good Samaritan turns out to be a diesel mechanic

There once was a fellow named Tim,
Who decided to stop on a whim,
And he started our van,
With some stuff from a can,
So we’re now on our way, thanks to him.

Tim refused payment for his roadside assistance, so we sent him along with one of the inflatable space aliens, Lou Wheeze, for his kids. Ros Well and A. Leeann and Gert Rude don’t seem to be suffering separation anxiety yet.
