1. Think of 'mean' = 'nasty'; then the meanings of 'beat' and 'whip'.But there are some puns I can`t get at:
1. - Why are chefs mean?
- because they beat the eggs and whip the cream.
2. - What did the ocean say to the shore?
- Nothing; It just waved.
2. Think of 'wave' as in the noun! (#2 isn't a very good pun, I'm afraid.)
Does that help?
