An engineer from Nuneaton may have let the opportunity for a pun carry him away slightly:

A Nuneaton engineer says he has been snowed under by orders for sledges built from car exhaust pipes.

…”I’ve had two orders from people stopping me to say: ‘I love that – can I have one?’.”

In later years as he looks back on his exhaust sledge empire he’ll no doubt reminisce how things snowballed from here. All the time he’s spending away from his family building these sledges must be leaving him on thin ice with his wife. His dogs must be exhausted etc…
