Self-study activity:
Enjoy the ads. They represent the latest publicity stunts in the US. You also have at your disposal tons of listening material.
If you wish, you can also take part in the interactive vote for the best ad that both The Wall Street Journal and MSNBC are holding.
Why don't you get together with an English-speaking friend or relative and discuss the adverts you liked the best/least. You can also take it in turns to be sitting with your back against the computer and get the other person to describe an ad.
