Wally and the Bead

Yes, you read that right.  Last night we went to the drive-in to see Wall-E.  Megan had a conversation with her dad earlier in the week about it.  Layne ended up mentioning something about Wally and the Beav - memories from a TV show of days gone past.  (I don't know what the connection is either.)  Apparently, it stuck with Megan - for the rest of the week she referred to the movie Wall-E as Wally and the Bead.  She had me questioning myself a couple of times.  Is there something about the title of this movie that I'm not aware of or is she just making something up?  (She is 4 - imagination is always a possibility.)  On the way to the movie, there were several times she enthusiastically stated, 'Wally and the Bead!'.  It was completely random and humorous all at the same time.  We love our Megan!  We count her as one of multiple entertainers in our family.
