Well, for me anyway, I'm sure other people will have had worse, with deaths and such.
Was late for my chemsitry exam as I thought it was in the afternoon and found it really hard (everyone else did too, thank heavens).
Then I lost my student card - found it in time for my biology exam in the afternoon though.
Kept messing up at work.
Did successfully make a human pyramid, got three people onto one person in a piggyback and cheered on an extremely amusing wheelbarrow race.
