yellowish urine on da bowl

There is few drops of urine on top my office's toilet bowl. Don't know whose urine is that, but there are only few 'candidates only.

Me, my colleague, accounts, store keeper, and my dearest BOSS.

Who will be da most suspectable one?

Let's guess. It's on the bowl but not the cover. So normally girls can't do that trick. So the most probably is......... Da guy. Who is th guy? Ermmmm.... THE ONE. Who else?

Many times already this kinda thing happend but it really very yellowish. Maybe too heaty yea? Haha...
