I don't get it

This evening at school was fun. We had a class 'party' at the canteen. Is was not like a real party actually. Its like hanging out with my classmates while eating. I ate pizza, panasanjing, thts all i guess? Im wondering, who was the one who named the food as 'hotdog'? Cant they put any other animal's name? Its better if there is no any animal's name. Its a food. Why should it called as a 'dog'? Whatever it is, it shouldn't be called 'hotdogs'. Maybe we can call em 'hotbeef'? Better. No no. Beef is better. A few days ago, i watched a programme in the television. The programme was about on how to make 'Tradisional kuih'. So, i watched. Then, there is one type of 'kuih' which tht guy used his foots and steped on tht 'kuih'. Errrr, disgusting. Can you imagine, he is an indian man. First, is his foots clean? Second, you shouldn't step on a food. Third, will you eat it? Yulk. Can't they just use their hands?
