(From my sketch book.) Someone might well recognise the news paper headline in front of the newsagent. It is lifted from the Doctor Who story The Web Of Fear, the Yeti in the Underground (How often does one get to say that?)story. The Doctor was only popping for some jelly babies and then he would be off. Jelly babies and the Blinovitch Limitation Effect do not mix. Like Dolly Mixtures and The Doppler I suppose...
