** Update - seems that half the tickets will be available 1 week before the event and the other half on the morning of the event which kind of makes things fairer **
Meet Bing and Flop throughout August and October at varous places around the country. Seems to be in The Entertainer and Toys R Us - they are ticketed events but totally free and you get stickers, play games with Bing and Flop and you get to take away a pair of Bing ears as well. Link takes you to all the details and how to get tickets but dates and venues are below.
