Head of Biology. That's a gift
loads of stuff on years of teaching reproduction and now your chance to put theory into practice
Address bride "has he shown you his birth control powerpoint yet" pause "did you make a selection...."
or "you'll need to get 80% on the reproduction test before this evening!
Or to him "I know your an expert on using birth control but you do know that out their in the real world it you don't actually unroll it on a banana"
If their quite a few teachers present things like "I'd like you to write down on the flip chart what your hoping to get out of my speech" its how all courses start
depending on the time of the speech you might manage a
"Oh look its 3:30, time for you to pack up and go home while the rest of use slave on for another couple of hours"
If you into the holiday ribbing. "I checked the contract you do know that you only work 195 days a year. That's a 170 days off ladies and gentlemen. Infact they only work 53% of the days of the year."
when you come to working in some positives its all about the kids lives they've enriched etc.
Oh finally a quote from a mate who is a biology teacher. He was walking through town and a mate stopped him an said "you taught me biology 20 years ago". I still remember what you said "reproduction is the fusing of a sperm and egg, any thing else is just a fringe benefit"
