I could have interchangeable arms, one with a Swiss army knife on the end, another with a air gun attachment that could shift the rustiest stuck on bolt ever then a power polisher attachment for buffing the hull (and other things!), a telescopic one so I can reach all those nuts I drop in the bilges and one with a big Fook off hammer on the end so I can get the engines going again when the Volvo man starts sucking air and 'should have called me sooner before you got the spanners out'.
