Have to duck out of the ridiculous 39C heat before I fry.
Scouting about for some shade leads us to the studios of Al Jazeera TV.We persuade the security bloke to hand over a phone number for their sports correspondent.
A couple of calls later and this suave telly fella is meeting us with a camera crew back outside the Mauritanian embassy, which I thought might would make a good setting to tell him about our trip across the continent. Wrong.
Seems these Mauritanians are quite a twitchy bunch, and a bit of a kerfuffle ensued as some puffy-chested security dudes bounced us out of the area.
Still, they’re doing a feature on The Thumb’s journey so that might improve our chances of getting lifts.
Very pleased to discover the vibe at the Mali Embassy could hardly be more different.
Thought we might be in trouble when a very, very large Malian gent takes us into a side room... only to introduce us to his mum and son!
We all end up sitting around this grand table having the craic while the officials sped through our paperwork in an hour...superb!
Nip into an internet café on the way back. A fella called Chouaib Kabbab – pronounced Schwibe – is in charge. He turns out to be a diamond, as well as a Moroccan kickboxing champion.
Chouaib quickly warms to our mission and is only too happy to help. He shows us Rabat local style, and arranges for us to kip on the floor at his mate Ismael’s place.
Chouaib is something of a Fonzy in his hood. It's a laid back but vibrant place where everyone knows his name, kids play in the street at midnight, old fellas smoking Shishas, pots of mint tea sit by their feet.
Chouaib also introduced us to some funky street vendors selling bread filled with brain, heart and liver, cooked up on a grill.
This might sound stomach turning, but it was actually delicious and – more importantly – cheap.
