They actually tried to light several real carrots and gave up after awhile, as they could not light it.

Once my next door neighbour smoked just outside his corridor. I supposed it was after dinner time. The odour lingered to ours. My 4 yo boy w/o asking stood before our gate and said aloud, " Hey, no smoking please! " hahah good initiative son.

Since then, my kind smoking neighbour now would stand near the rubbish area for his puffing session. Thank god, he got the message.
