Now Goldie is just showing off his flexibility. Dave can try, but he just can't compete on the same level as Goldie when it comes to flexibility. Dave's relative inferiority in this area probably has a something to do with Dave's love of food.
Although Goldie clearly excels at this, there is still a lot he could learn from Dave. Dave doesn't care that much about flexibility anyway, preferring to focus instead on creative napping.
