Finally, last night was the night when we were home and the kitchen was clean and I had time to help him make the cake for his bears. He helped to beat it, and thought it was amusing how fast I can turn the batter. When it came time to do the frosting, he wanted to be quick like me, but I cautioned him to go slow so the sugar wouldn't fly out of the bowl, and he changed tactics and the counter was only lightly dusted. He wondered how we got vanilla frosting, but when I let him smell the bottle, he knew the smell immediately. I remember when I was a kid being so disappointed at the taste of it. He must have already had a taste, because he had no interest until it had been mixed in.
When it was cooled and frosted with the words, "Happy Birthday, Truckers and Fluffy Jack!", we sang the song, and Emmett blew out two candles. When we asked him how old they were he replied, "Fifty!" Apparently age is a pretty fluid concept as well. We dug in to our cake and enjoyed the sweet treat. Eventually Emmett said, "Hey! You forgot their presents, they're feeling sad!"
I'm thinking with that he revealed the modus operandi for this little celebration. At least he got cake out of the deal!
