Led Zeppelin & Bunny Rabbits - Day Four

Knock knock
Who's there?
'Trampled Underfoot'
'Trampled Underfoot' who?
Greg – happened over at the carriage crossing

Note: Because of the graphic nature of this knock-knock joke, we have selected the 'small' size of photo. YOTK reminds you to be careful when crossing streets, avenues, by-ways and boulevards. Lanes and cul-de-sacs shouldn't be a problem.
