Cambridge for one night (20th)

Had a great time with Rohan an Irish guy and two of the girls from the hostel; Lucy (Poland) and Isabel (German/France).
For the first half of the evening Rohan and I sat in on a german school group relating the interviews they'd had with english speaking people around cambridge that day. Really funny stories. One particular girl was totally clueless and answered in the following ways
a) how many people in Cambridge
'I don't know, maybe 10,000?' (there are over 100k)
b) what do you like about Cambridge
'It's really easy to get weed' (teachers loved that one)
c) do you know any of the hisory of Cambridge
'Well the river is called Cam, and I guess there's a bridge over it, but I don't know which came first, the river or the bridge' (Not too often you redirect a river under an existing archway...)
and then a very offensive thing about the stereotypical german.
Rohan and the girls then stayed up chatting away and playing cards ('thief') which was most enjoyable except for one particular twit called John who decided he wasn't getting enough attention so he popped an E, and then acted like an even bigger dick for the rest of the night.
