dave likes  Sick beats, phat rhymes, weird preserved dead things, irony and hates puppets
dave, despite all of his joking around seems to always take things generally seriously if needed, which also leads him to suppress any other emotion so they don't get in his way. Also later Dave expresses deep unwillingness to use his time powers because he doesn't want to abuse them which shows how mature Dave actually is.Underneath his cool facade he appears to be rather caring towards animals
