Just read this thread on the SUP forum:

I dunno
but looking at the pic, and using my well developed sense of observation and powers of deduction - the bottom two are smaller than the top one
I think a superhero's arch enemy did it, using a shrinking ray ?
Reminds me of the irishman who takes his goldfish to the vet and say "I think it has epilepsy"
The vet replies " It look just fine to me Mick"
Mick replies "Hold on a minute, I haven't taken it out of the bowl yet...."
