Speaking of Math and innovative thinking

Looking for an innovative interpretation of a Math problem, or indeed any problem then have a look at this great clip proving that 7 x 13 = 28. If you don't believe me have a look at Abbot_and_Costello_Maths_Problem found on the site Teacher Tube. Teacher Tube is a You Tube for teachers with lots of great clips (and many not so good) that will prove useful to teachers.
