TC gets on the sled without even taking off his comforter.
The whole point of the episode is TC telling Dibble that he and the gang violated a law by living in the alley (living on public property), which we learn at the end of the episode was a trick by TC (the law they "broke" was repealed in 1936). The police would have known the law was repealed and would've arrested TC and the gang for trying to live in Dibble's house.
