Pauls post brought someone to mind.
Mr. Ed Sinchak was my tenth grade art teacher. He too was an old hippie....Well, he was in his 40s at the time, so...."old" to me. Anyhow, Mr. Sinchak often pretended to not know we were smoking weed in the supply room. This was all unwittingly done because it was believed that weed enhanced our artistic abilities.
To keep it short, we had an art show that year. When my old man saw the class exhibit, a ten foot tall purple Tyrannosaurus Rex, sporting mirrored shades, gold chains, a fedora with a large green feather and smoking a cigar named "Sweet Daddy T. Rex". He looked me right in the eye and said;
"Let me guess. It's reefer, isn't it?"
