I just found a new one, a real groaner, while reading a recent post--
sorry, can't find it again to give credit.  I missed the pun when 
reading the relevant passage originally. 

Uncle Algie who gave Neville the _Mimbulus mimbletonia_ plant.  Uncle 
Algie, who must also have inheritied the Longbottom talent for 
herbology.
