I've got mascara tears streaming down my face! I can SO relate to starting with one thing in mind only to have things go down hill, gaining momentum as they go.
While the story was really funny, the cake wasn't so bad. It's times like these that I think of Pee Wee Herman in Pee Wee's Big Adventure when he tried to do a trick on his bike and fell down. I can hear him saying, "I meant to do that"!!
As long as you're having fun, then everything is going to be OK.
