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 Waterskiing' 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.
