LMSCO

laughing my stem cells off
laughing so hard the unspecialized cells in your bone marrow are being metaphorically emmitted.

2 atoms are walking across the road, one says to the other; "hey, i think i just lost an electron"
the other says;
"really? are you sure?"
the 1st says;
"yeah, i'm absolutely positive!"

hahaha!! LMSCO!!!
