Some people might say that collecting vintage toasters is a crumby hobby.

有人可能觉得收集复古烤面包机不够高端。

The thing is that crumby foods are understandably not allowed on the space station because stray crumbs can damage the equipment.

上可以理解，裹了面包屑食物不允许带上空间站，散食物碎屑可以破坏设备。

As for the gingerbread men, their eternity may be pretty crumby, but so long as they go out on a limb, their friendship will never again be half-baked.

至于姜饼人，他们永恒可能很脆弱，但只要他们勇敢地走出去，他们友谊就不会再半生不熟。
