P-tatoes love to tatoe with P's. P's are pretty rare on the planet GNPFLGRDFPL. P's grow only very slowly in P'tuniafields which have a special chemical composition. P's are the only non-domesticated letters on the planet. If a P-tatoe finds a P they form a partnership immediately. To be exact, the P-tatoe runs to the P and clasps firmly to it. From this moment on they are not to be separated. So far nobody checked whether they actually grow attached to become one.
