M: Now, your mum put me in charge of dinner because shes not feeling well tonight. W: But what is it... and that smell? M: Its pizza. I just followed an old family recipe here, and... W: Let me see that... Oh, Dad. M: What? W: Youre missing a page! M: Oh, uh, well, uh... well I couldnt find the second page of the recipe, but dont worry. I have plenty of experience around the house. Plenty of experience of cooking. W: Thats not what mum says. M: Well, wait, wait. Here let me try a piece first. Here, let me, let me cool this off here. Oh, yeah. Oh, this is great stuff. W: Yeah right. Why are you making that face? M: Well, well, its just, just a little rich for me. Thats all. W: Let me try it, Dad. Uh, Dad. You put a little too much salt in it and besides its burned. M:Well... W: And whats that? M: Oh, well, well, thats just part of my own adaptation to the recipe. I added some pumpkin. W: Oh, not another one of your surprises. Pumpkin doesnt go on pizza! M: Well, okay, well, so what? Uh, what do we do now? W: Well, how about some cold cereal... You cant mess up on that, Dad.
