Yeah, Rodrigo doesn't mean to do it but his uncontrollable laugh gets him in trouble every time.
It was hysterical when Roddy said that they could cut it down to just the one camera pointed at the bustop!
If it was anyone else David would have been doing his ridiculously fake 'laugh' and Lisa would have been grinning smuggly but they don't like it when the tables are turned.
A classic case of people who can give it out but can't take it in return.
