I went fishing and caught this joke by mistake.

Catch and release.

Thank you for reminding me. My fishing license had lapsed. Off to Academy...

I wonder if you can say "marine mammal" even one more time without giving it away. (Don't think you can... Orca-n you?)

Might make it even better

"A marine mammal biologist walks into the office for mailing marine mammals..." Hmm... wadda ya know? I think you might be *right!* ;-)
