One explanation for Sirius Black being found laughing like a loon

has not, as far as
I know, been put forward:  A Cheering Charm.
Even though, _compared to his three pals who were some of the best in 
their year,_ Peter Pettigrew is not much of a spell-flinger, a 
Cheering Charm should be well within his capabilities.

Nice theory Eric. To be honest, the events of that fateful night and 
Sirius' role/behaviour at the time is something that's driving me up 
the wall (is there a counter curse for that?!). 

So, OK, Fudge was one of the first ones on the scene and it was 
claimed that Sirius was found laughing his head off, but we've been 
going over and over this and I'm still not convinced this is what 
really happened. 
Isn't it true that once people suspect someone to be evil they find 
it very easy to attribute a few nasty characteristics to that person, 
and readily accept any 'facts' when they are nothing but fiction 
added by excited gossipers?(or, as in Fudge's case perhaps, to make 
it more convincing).  That night made Sirius a legend in the 
wizarding world - a story like that could easily start living a life 
of its own.
