I saw a friend make these once and then copied her;
You need uncooked spaghetti and hot dogs to start.
Cut up hot dogs into 1" lengths, break spaghetti noodles into 3" lengths. Stick 4 noodles into rhe hotdog so that they stick out and make 8 "legs" total. Drop gently into boiling water until the noodles cook - only a moment or two.
Serve as is or with sauce.
We call them spider-weenies. :-)
