There was not enough snow for Hulk to shovel and make extra pocket money so he can buy presents for his friends like the man at the donut place that makes sure Hulk has an extra big coffee and Captain America who is a very nice person except when he is all bossy and that makes Hulk sad.
If Hulk could feel strong and brave about doing it, Hulk would make a computer frowny face like this :( but Hulk can not.
