10 Funniest UK ads of the 70s

There aren't many funny ads these days - but there were back in the 70s. Here are 10 from the UK, where agencies CDP and BMP held sway. Dates are a bit vague:
1. PG Tips 'Mr Shifter' - Davidson Pearce, 1971
2. Benson & Hedges Small Cigars 'Istanbul' - CDP, 1972
3. Nescafe Fine Blend 'Tap' - Don't know the agency, 1974
4. Smash 'Martians' - BMP, 1974
5. Parker Pens "Finishing School' - CDP, 1976
6. Heineken 'Caesar Water-skiing' - CDP, 1978
7. John Smith's Bitter 'Hikers' - BMP, 1978
8. Dry Cane 'Ashtray' - BMP, 1978
9. Cinzano 'Tiger' - CDP, 1979
10. Campari 'Luton Airport' - JWT, 1979

Interesting that 7 of them are for drinks of one sort or another.
